PREFACE,The <strong>zoological</strong> collecti<strong>on</strong>s <strong>made</strong> dur<strong>in</strong>g <strong>the</strong> Survey<strong>in</strong>g-voyage ofH.M.S. * Alert ' <strong>in</strong> <strong>the</strong> years 1878-82, under <strong>the</strong> command ofCapt. Sir G. Nares and his successor Capt. J. Maclear, werepresented by <strong>the</strong> Lords Commissi<strong>on</strong>ers of <strong>the</strong> Admiralty to <strong>the</strong>Trustees of <strong>the</strong> British Museum.A narrative of <strong>the</strong> voyage has been given by Staff-Surge<strong>on</strong>R. W. Copp<strong>in</strong>ger, <strong>in</strong> his work ' Cruise of <strong>the</strong> ' Alert ' ' (L<strong>on</strong>d<strong>on</strong>,1883, 8vo).^ The pr<strong>in</strong>cipal parts of <strong>the</strong> Survey, and c<strong>on</strong>sequently <strong>the</strong>Collecti<strong>on</strong>s, fall <strong>in</strong>to three dist<strong>in</strong>ct secti<strong>on</strong>s, viz. :— 1, that of<strong>the</strong> Sou<strong>the</strong>rn extremity of <strong>the</strong> American c<strong>on</strong>t<strong>in</strong>ent; 2, that of<strong>the</strong> coasts of i^orth-eastern Australia and Torres Straits : and3, that of <strong>the</strong> groups of <strong>Ocean</strong>ic Islands <strong>in</strong> <strong>the</strong> Western Indian<strong>Ocean</strong>, situated between <strong>the</strong> Seychelles and Madagascar.The first of <strong>the</strong>se collecti<strong>on</strong>s has already been reported up<strong>on</strong> <strong>in</strong>Proo. Zool. Soc. 1881 ; but <strong>the</strong> two o<strong>the</strong>rs surpass it so much<strong>in</strong> extent and importance as to be quite bey<strong>on</strong>d <strong>the</strong> scope of aperiodical publicati<strong>on</strong>, and <strong>the</strong>refore <strong>the</strong> Trustees c<strong>on</strong>sidered itbest that a full account of <strong>the</strong>m should be prepared <strong>in</strong> <strong>the</strong> formof a separate work. With <strong>the</strong> excepti<strong>on</strong> of <strong>the</strong> 'Challenger'Expediti<strong>on</strong>, n<strong>on</strong>e of <strong>the</strong> recent voyages has c<strong>on</strong>tributed so mixchto our knowledge of <strong>the</strong> Littoral Invertebrate Fauna of <strong>the</strong> <strong>Indo</strong>-<strong>Pacific</strong> <strong>Ocean</strong> as that of <strong>the</strong> ' Alert.' Irrespective of a iramber ofspecimens set aside as duplicates, not less than 3700, referableto 1300 species, were <strong>in</strong>corporated <strong>in</strong> <strong>the</strong> Nati<strong>on</strong>al Collecti<strong>on</strong> ; and

;VIPREFACE.of <strong>the</strong>se more than <strong>on</strong>e third (490) were new additi<strong>on</strong>s, if not toscience, at any rate to <strong>the</strong> Museum.The hest thanks of zoologists are due to <strong>the</strong> Lords of <strong>the</strong>Admiralty, to <strong>the</strong> late Hydrographer, Capt. Sir F. Evans, K.C.B.,and to <strong>the</strong> Commanders of <strong>the</strong> ' Alert,' from whom Dr. Copp<strong>in</strong>gerreceived every encouragement <strong>in</strong> <strong>the</strong> prosecuti<strong>on</strong> of his <strong>zoological</strong>work.F<strong>in</strong>ally, although <strong>the</strong> follow<strong>in</strong>g pages are by <strong>the</strong>mselves alast<strong>in</strong>g testim<strong>on</strong>y to <strong>the</strong> great service rendered by Dr. Copp<strong>in</strong>gerto <strong>the</strong> Nati<strong>on</strong>al Museum and to <strong>the</strong> cause of science, I must notallow this opportunity to pass without duly acknowledg<strong>in</strong>g <strong>the</strong>energy and skill with which he performed this work. The collecti<strong>on</strong>swere <strong>made</strong> with s<strong>in</strong>gular judgment, <strong>the</strong> specimens (many of<strong>the</strong>m most fragile and delicate) preserved, labelled, and packedwith <strong>the</strong> greatest care ; and, beside, full lists wore prepared by himgiv<strong>in</strong>g additi<strong>on</strong>al, and <strong>in</strong> many cases most valuable, <strong>in</strong>formati<strong>on</strong>.When we bear <strong>in</strong>m<strong>in</strong>d that all this work was d<strong>on</strong>e <strong>in</strong> <strong>the</strong> leisurehours which Dr. Copp<strong>in</strong>ger could spare from his strictly officialduties, we may be encouraged <strong>in</strong><strong>the</strong> hope that <strong>on</strong> future occasi<strong>on</strong>ssimilar advantage will be taken of <strong>the</strong> opportunity which a voyageof Survey offers to q, man of science.The collecti<strong>on</strong>s were worked out immediately after <strong>the</strong>ir arrivalbut <strong>the</strong> completi<strong>on</strong> of this Eeport was c<strong>on</strong>siderably delayed by <strong>the</strong>removal of <strong>the</strong> Department from Bloomsbury to South Kens<strong>in</strong>gt<strong>on</strong>.ALBEET GUNTHER,British Museum,June 20, 1884.Keeper of <strong>the</strong> Department of Zoology^

THEZOOLOGICALCOLLECTIONSojH.M.S.'ALERT.'SUMMARY OF THE VOYAGE.BYR. W. COPPINGER, M.D., Staff-Surge<strong>on</strong> R.N.Dur<strong>in</strong>g <strong>the</strong> summer of 1878 it was resolved by <strong>the</strong> Admiralty toequip a vessel for <strong>the</strong> performance of special survey<strong>in</strong>g-work <strong>on</strong><strong>the</strong> western shores of Patag<strong>on</strong>ia, am<strong>on</strong>g <strong>the</strong> South-<strong>Pacific</strong> Islands,and <strong>on</strong> <strong>the</strong> eastern and nor<strong>the</strong>rn shores of Australia; <strong>in</strong> additi<strong>on</strong>to which, it was <strong>the</strong> wish of <strong>the</strong> Hydrogra])her of <strong>the</strong>Navy, Capta<strong>in</strong> (now Sir Frederick) Evans, F.R.S., that no opportunityshould be lost of collect<strong>in</strong>g objects of natural history whenever<strong>the</strong> requirements of <strong>the</strong> survey brought <strong>the</strong> vessel <strong>in</strong>to regi<strong>on</strong>swhose zoology was hi<strong>the</strong>rto but imperfectly known. It was <strong>in</strong>accordance \vith <strong>the</strong>se views that <strong>on</strong> <strong>the</strong> 20th August, 1878, H.M.S.'Alert' was commissi<strong>on</strong>ed at Sheerness, with a complement of120 officers and men, by Capta<strong>in</strong> Sir George IS'ares, who, by a happyco<strong>in</strong>cidence, had commanded <strong>the</strong> same vessel <strong>in</strong> <strong>the</strong> Polar Expediti<strong>on</strong>of 1875-76. On <strong>the</strong> 20th of <strong>the</strong> follow<strong>in</strong>g m<strong>on</strong>th we sailed fromPlymouth.On <strong>the</strong> outward voyage we touched for a few days at Madeira andSt. V<strong>in</strong>cent respectively ; and at both of <strong>the</strong>se places some shallowwaterdredg<strong>in</strong>g was accomplished, result<strong>in</strong>g <strong>in</strong> <strong>the</strong> acquisiti<strong>on</strong> of asmall collecti<strong>on</strong> of mar<strong>in</strong>e <strong>in</strong>vertebrates, <strong>in</strong> which, as might havebeen expected, <strong>the</strong>re was little, if any th<strong>in</strong>g, of special <strong>in</strong>terest.B

—Z VOYAGE OF H.M.3. ' ALERT.Dur<strong>in</strong>g our fur<strong>the</strong>r voyage through <strong>the</strong> South Atlantic a coursewas held which brought us over <strong>the</strong> Hotspur and Victoria Bankssubmei-ged coral-reefs which are situated between <strong>the</strong> parallels ofITg" and 12° S. lat., and are about ISO miles from <strong>the</strong> east coast ofBrazil. In <strong>the</strong>se two places we plied our dredges <strong>in</strong> depths rang<strong>in</strong>gfrom 35 to 39 fathoms, obta<strong>in</strong><strong>in</strong>g <strong>the</strong>reby a large number of <strong>zoological</strong>specimens, am<strong>on</strong>g which were several novelties <strong>in</strong> <strong>the</strong> classesof Sp<strong>on</strong>ges and Polyzoa. The collecti<strong>on</strong> <strong>made</strong> at <strong>the</strong>se stati<strong>on</strong>sproved to be of special <strong>in</strong>terest, as it helped to fill up a gap unavoidablyleft by <strong>the</strong> Challenger ' ' expediti<strong>on</strong> <strong>in</strong> <strong>the</strong> mar<strong>in</strong>e zoology of<strong>the</strong> South Atlantic.On <strong>the</strong> 27th November we anchored <strong>in</strong> <strong>the</strong> esti;ary of <strong>the</strong> riverPlate, off M<strong>on</strong>te Video, where we rema<strong>in</strong>ed until <strong>the</strong> 14th December.Sail<strong>in</strong>g <strong>on</strong> <strong>the</strong> latter date, we shaped a course for <strong>the</strong> FalklandIslands, and arrived at Stanley Harbour <strong>on</strong> <strong>the</strong> 26th <strong>in</strong>st. A fewweeks prior to <strong>the</strong> time of our visit to <strong>the</strong> Falklands a peculiaravalanche of semifluid peat had poured down from <strong>the</strong> summitof <strong>on</strong>e of <strong>the</strong> low hills, lay<strong>in</strong>g waste a porti<strong>on</strong> of <strong>the</strong> settlement.AVe aga<strong>in</strong> put to sea <strong>on</strong> <strong>the</strong> even<strong>in</strong>g of <strong>the</strong> 27th December, andsteer<strong>in</strong>g to <strong>the</strong> eastward, entered <strong>the</strong> Strait of ]\[agellan <strong>on</strong> <strong>the</strong>first day of <strong>the</strong> year 1S79. After stopp<strong>in</strong>g for a few days at <strong>the</strong>Chilian settlement of Sandy Po<strong>in</strong>t, we proceeded to our survey<strong>in</strong>ggroundam<strong>on</strong>g <strong>the</strong> channels <strong>on</strong> <strong>the</strong> west coast of Patag<strong>on</strong>ia. Herewe spent <strong>the</strong> greater porti<strong>on</strong> of <strong>the</strong> two succeed<strong>in</strong>g years, execut<strong>in</strong>gsurveys of previously uncharted waters, and add<strong>in</strong>g to those whichhad been partially eflPected by our predecessors <strong>in</strong> <strong>the</strong> same field ;but dur<strong>in</strong>g <strong>the</strong> more rigorous w<strong>in</strong>ter m<strong>on</strong>ths we each year proceedednorth to Coquimbo, <strong>on</strong> <strong>the</strong> Chilian coast, where our ship was refittedand fresh supplies of stores were obta<strong>in</strong>ed *. As <strong>the</strong> requirementsof <strong>the</strong> survey necessitated our visit<strong>in</strong>g and anchor<strong>in</strong>g <strong>in</strong> a greatmany bays and <strong>in</strong>lets <strong>in</strong> this remote regi<strong>on</strong>, frequent opportunitiesoccurred for shallow-water dredg<strong>in</strong>g, so that we were able to makea large collecti<strong>on</strong> of mar<strong>in</strong>e <strong>in</strong>vertebrates— a branch of research towhich our attenti<strong>on</strong> was more especially directed, as we were awarethat <strong>in</strong> o<strong>the</strong>r departments of biology <strong>the</strong> work d<strong>on</strong>e by <strong>the</strong> Erebus ''and ' Terror,' ' Nassau,' and Challenger ' ' of our own navy, as wellas by many foreign vessels, left little to be desired.Dur<strong>in</strong>g <strong>the</strong> m<strong>on</strong>th of March 1880 a visit extend<strong>in</strong>g over a fewdays was <strong>made</strong> to Skyr<strong>in</strong>g Water, a large and almost completelylandlocked sheet of water situated to <strong>the</strong> eastward of <strong>the</strong> Cordillera,and, so far as we yet know, <strong>on</strong>ly accessible by ship through anarrow channel by which it communicates with <strong>the</strong> ma<strong>in</strong> Strait ofMagellan. And here I should remark that <strong>in</strong> <strong>the</strong> m<strong>on</strong>th of July1879, and dur<strong>in</strong>g <strong>the</strong> surplus time allotted for refitt<strong>in</strong>g our ship <strong>on</strong><strong>the</strong> Chilian coast, a brief visit was <strong>made</strong> to <strong>the</strong> island of St. Ambrose,which lies about 500 miles to <strong>the</strong> north-west of Coquimbo.* Dur<strong>in</strong>g <strong>the</strong> w<strong>in</strong>ter of 1879-80 Sir George Nares returned to England, andwas succeeded <strong>in</strong> <strong>the</strong> command of <strong>the</strong> 'Alert ' by Capta<strong>in</strong> Maclear, formerly of<strong>the</strong> Challenger ' ' Expediti<strong>on</strong>.

eiTMMARr. 3Ou <strong>the</strong> 14th June, 1880, we bade adieu to <strong>the</strong> South-Americaacoast and sailed for Tahiti, spend<strong>in</strong>g much time <strong>on</strong> <strong>the</strong> way <strong>in</strong>search<strong>in</strong>g for <strong>the</strong> so-called M<strong>in</strong>erva Eeef, which was reputed toexist some 60 miles to <strong>the</strong> north-east of Manga Eeva, <strong>on</strong>e of <strong>the</strong>Paumotu group. Arriv<strong>in</strong>g at Tahiti <strong>on</strong> <strong>the</strong> 6th of August, we <strong>made</strong>a stay of twelve days at that <strong>in</strong>terest<strong>in</strong>g island, when we aga<strong>in</strong> gotunder way and pursued a circuitous route towards <strong>the</strong> great Fijigroup.The first place at which we touched <strong>on</strong> this voyage was NassauIsland, whence we proceeded to <strong>the</strong> Uni<strong>on</strong> group, <strong>in</strong> 80^° S. lat.,pass<strong>in</strong>g with<strong>in</strong> sight of Tema Reef and <strong>the</strong> Danger Islands, whichwere found to be <strong>in</strong>correctly placed <strong>on</strong> <strong>the</strong> charts. We <strong>made</strong> a shortstay at Oatafu, <strong>the</strong> most westerly island of <strong>the</strong> Uni<strong>on</strong> group, and<strong>the</strong>nce proceeded to Fiji.We anchored off <strong>the</strong> settlement of Levuka <strong>in</strong> <strong>the</strong> island of Ovalau,Fiji, <strong>on</strong> <strong>the</strong> 18th of September, and rema<strong>in</strong>ed <strong>the</strong>re until <strong>the</strong> 10thof October, We <strong>the</strong>n steamed over to T<strong>on</strong>gatabu, <strong>in</strong> <strong>the</strong> FriendlyIslands, where wo <strong>made</strong> a pleasant stay of ten days, but subsequentlyspent some very dull weeks, aggravated by unusuallyboisterous wea<strong>the</strong>r, <strong>in</strong> an uneventful search for <strong>the</strong> La Eance Bank,<strong>the</strong> n<strong>on</strong>-existence of which was, however, satisfactorily dem<strong>on</strong>strated.We returned to Levuka <strong>on</strong> <strong>the</strong> 4th of December, andrema<strong>in</strong>ed <strong>in</strong> harbour for ten days, when we entered up<strong>on</strong> <strong>the</strong> lastporti<strong>on</strong> of our <strong>Pacific</strong> cruise, viz. <strong>the</strong> voyage from Fiji to Sydney.We arrived at Sydney <strong>on</strong> <strong>the</strong> 23rd of January, 1881, and rema<strong>in</strong>ed<strong>the</strong>re, refitt<strong>in</strong>g, until <strong>the</strong> 15th of April, when we steamedup <strong>the</strong> east coast of Australia to our next survey<strong>in</strong>g-ground.Dur<strong>in</strong>g <strong>the</strong> ensu<strong>in</strong>g six m<strong>on</strong>ths we visited Port Curtis, PortMoUe, and Port Denis<strong>on</strong> <strong>on</strong> <strong>the</strong> east coast of Queensland ; LizardIsland, Fl<strong>in</strong>ders Island, Clack Island, Bird Island, Percy Islands,Clairem<strong>on</strong>t Islands, and Albany Island, adjo<strong>in</strong><strong>in</strong>g <strong>the</strong> coast ; andwhile engaged <strong>on</strong> <strong>the</strong> survey of <strong>the</strong> Pr<strong>in</strong>ce of Wales Channel, <strong>in</strong>Torres Straits, we anchored off Wednesday, Thursday, Friday,Home, West, Pr<strong>in</strong>ce of Wales, Hamm<strong>on</strong>d, Goode, and Booby-Islands. In aU <strong>the</strong>se localities mar<strong>in</strong>e specimens were collected, aswell as <strong>in</strong> <strong>the</strong> more open parts of <strong>the</strong> Pr<strong>in</strong>ce of Wales Channel,where <strong>the</strong> depth rarely exceeds 30 fathoms. A good many <strong>in</strong>terest<strong>in</strong>gspecimens were also obta<strong>in</strong>ed through <strong>the</strong> assistance of <strong>the</strong>pearl-shell divers, who have an extensive and lucrative <strong>in</strong>dustry <strong>in</strong><strong>the</strong>se waters.On leav<strong>in</strong>g this channel we proceeded westwards through <strong>the</strong>Arafura Sea, sound<strong>in</strong>g and dredg<strong>in</strong>g, until we reached Port Darw<strong>in</strong>,<strong>in</strong> North-west Australia. Here we rema<strong>in</strong>ed from <strong>the</strong> 3rd to <strong>the</strong>ISth of November, when we aga<strong>in</strong> got under way and steamedthrough <strong>the</strong> Eastern Archipelago to S<strong>in</strong>gapore. We reached thisport <strong>on</strong> <strong>the</strong> 18th November, 1881, and rema<strong>in</strong>ed <strong>the</strong>re for two anda half m<strong>on</strong>ths, spend<strong>in</strong>g most of <strong>the</strong> time <strong>in</strong> dock, where ourship underwent an extensive refit.

On <strong>the</strong> next day we steamedover to Mahe, <strong>the</strong> chief island of <strong>the</strong> group. After some days spen<strong>the</strong>re <strong>in</strong> provisi<strong>on</strong><strong>in</strong>g and coal<strong>in</strong>g <strong>the</strong> ship, dur<strong>in</strong>g which time ourboats did some useful dredg<strong>in</strong>g <strong>in</strong> <strong>the</strong> channel between Mahe andSt. Anne's Islands, we steamed over to <strong>the</strong> Amirante group, <strong>the</strong> mostnor<strong>the</strong>rly of which is <strong>on</strong>ly about a day's run from Mahe, \Ye hadorders to make a survey of <strong>the</strong> Amirantes, and, as far as time wouldpermit, of <strong>the</strong> o<strong>the</strong>r coral islailds which extend <strong>the</strong>nce <strong>in</strong> an irregularcha<strong>in</strong> southward towards Madagascar.The Amirante group c<strong>on</strong>sists altoge<strong>the</strong>r of twenty-<strong>on</strong>e low coralislets, rest<strong>in</strong>g, with <strong>the</strong> excepti<strong>on</strong> of He des Eoches (which is separatedby a deep channel), <strong>on</strong> an extensive coral bank, which is 89miles <strong>in</strong> length, with an average breadth of 19 miles, and whosel<strong>on</strong>g axis lies <strong>in</strong> a N,N.E. and S.S.W. directi<strong>on</strong>. It is <strong>in</strong>cluded between<strong>the</strong> limits of 4° 50^' and 6° 12^-' S. lat., and 53° 45' and52° 50|' E. l<strong>on</strong>g., and is thus about 700 miles distant from <strong>the</strong>nearest part of <strong>the</strong> East-African coast. Some of <strong>the</strong> islets andsand-cays of which it is composed, and which are <strong>in</strong>cluded <strong>in</strong> <strong>the</strong>above enumerati<strong>on</strong>, are so arranged <strong>in</strong> clusters that for all practicalpurposes <strong>the</strong> group may be regarded as c<strong>on</strong>sist<strong>in</strong>g of n<strong>in</strong>e islets,which have been named African, Eagle, Darros, Des Roches, Poivre,Etoile, Marie Louise, Des Neufs, and Boudeuse Islands.From <strong>the</strong> Amirantes we moved over to Alph<strong>on</strong>se Island, whichoccupies an isolated positi<strong>on</strong> (50 miles S.W. by S. of <strong>the</strong> sou<strong>the</strong>rn,extremity of <strong>the</strong> Amirante Bank ; and <strong>the</strong>nce proceeded to ProvidenceIsland, which is about 240 miles from <strong>the</strong> Amirantes <strong>in</strong>a S.W. by S. directi<strong>on</strong>, and about 2(J0 miles from Cape Amber, <strong>in</strong>Madagascar. After a short stay at each of <strong>the</strong>se islands, we steamedover to <strong>the</strong> Glorioso group, which c<strong>on</strong>sists of three islands, also ofcoral formati<strong>on</strong>, and situated about 120 miles W. by N. of <strong>the</strong>nor<strong>the</strong>rn extremity of Madagascar. Every effort was <strong>made</strong> to<strong>in</strong>vestigate <strong>the</strong> fauna and flora of <strong>the</strong>se islands as far as time ando<strong>the</strong>r circumstances would permit, so that sufficient materials wereaccumulated to c<strong>on</strong>nect <strong>the</strong>ir natural history with that of Seychellesto <strong>the</strong> northward and Madagascar to th^ southward.With our departure from <strong>the</strong> Glorioso Islands <strong>the</strong> survey<strong>in</strong>g operati<strong>on</strong>sof <strong>the</strong> ' Alert ' were brought to a close. On <strong>the</strong> 12th of Maywe reached Mozambique, whence, after a stay of a few days, weproceeded <strong>on</strong> our homeward voyage, stopp<strong>in</strong>g en route at AlgoaBay,Sim<strong>on</strong>'s Baj^, Cape of Good Hope, St. Helena, and Fayal (<strong>in</strong> <strong>the</strong>Azores), and arrived <strong>in</strong> Plymouth Sound <strong>on</strong> <strong>the</strong> 3rd of September,1882, after an absence of nearly four years.

He appears to me to have arguedfrom immature specimens when he tries to show <strong>the</strong> variati<strong>on</strong> of<strong>the</strong> species and attempts to prove that <strong>the</strong>y run <strong>on</strong>e <strong>in</strong>to ano<strong>the</strong>r.If it were possible to f<strong>in</strong>d <strong>in</strong> <strong>the</strong> same island examples of <strong>the</strong>se Pachycephalcewith <strong>the</strong> black breast-band united to <strong>the</strong> ear-covertsand o<strong>the</strong>rs with this disunited, all be<strong>in</strong>g fidly adult birds, <strong>the</strong>n Dr.Gadow would have proved his po<strong>in</strong>t ; but this is exactly what doesnot take place, <strong>the</strong> difference <strong>in</strong> colorati<strong>on</strong> be<strong>in</strong>g accompanied by adifferent habitat. It is not right to compare immature birds of <strong>on</strong>eform with adults of ano<strong>the</strong>r, because <strong>in</strong> <strong>the</strong>ir young stages all <strong>the</strong>sespecies are unquesti<strong>on</strong>ably very difficult to dist<strong>in</strong>guish apart ; but iffully adult birds are compared, I do not th<strong>in</strong>k <strong>the</strong>re ought to beany difficulty <strong>in</strong> determ<strong>in</strong><strong>in</strong>g four dist<strong>in</strong>ct species.Aga<strong>in</strong>, with regard to his observati<strong>on</strong>s that <strong>the</strong> colour<strong>in</strong>g of <strong>the</strong>upper tail-coverts " is of no specific importance," some attenti<strong>on</strong>must be given to <strong>the</strong> age and c<strong>on</strong>diti<strong>on</strong> of <strong>the</strong> specimens. In<strong>the</strong> group with <strong>the</strong> upper tail-coverts black, it will be found that<strong>the</strong> basal <strong>on</strong>es are always more or less tipped with olive, and thatit is <strong>the</strong> l<strong>on</strong>g <strong>on</strong>es which are black. If, <strong>the</strong>refore, <strong>the</strong> latter areshot away, a superficial observer would jump at <strong>on</strong>ce to <strong>the</strong> c<strong>on</strong>clusi<strong>on</strong>that <strong>the</strong> upper tail-coverts are olive-yellow. Even <strong>in</strong> this case<strong>the</strong> yellow-washed quills (<strong>in</strong>stead of grey) would enable <strong>on</strong>e to dist<strong>in</strong>guish<strong>the</strong> P.-macrorhgncha group from P. mekmura. Then,aga<strong>in</strong>, it would appear from moult<strong>in</strong>g specimens that <strong>the</strong> upper tailcovertswhen first grown have more olive-yellow <strong>on</strong> <strong>the</strong> marg<strong>in</strong>sthan <strong>in</strong> <strong>the</strong> fully adult bird. Therefore <strong>in</strong> <strong>the</strong>se Pach/ycephalce, as<strong>in</strong> o<strong>the</strong>r birds, <strong>on</strong>ly fully plumaged specimens should be compared,if <strong>on</strong>e is to understand <strong>the</strong> relati<strong>on</strong>s of <strong>the</strong> various species.There can be no doubt that <strong>the</strong> locality " Celebes " attached to<strong>the</strong> specimen from <strong>the</strong> Gould Collecti<strong>on</strong> is err<strong>on</strong>eous ; and Mr.Wallace has remarked <strong>on</strong> <strong>the</strong> absence of <strong>the</strong> genus <strong>in</strong> <strong>the</strong> aboveisland, <strong>in</strong> <strong>the</strong> essay quoted by Dr. Gadow.

—;;22 COLLECTIONS l^'ROM MELANESIA.This <strong>in</strong>terest<strong>in</strong>g specimen is not easy to determ<strong>in</strong>e, be<strong>in</strong>g <strong>in</strong> sizelike D. cerv<strong>in</strong>us and <strong>in</strong> colour like D. leacliii. As I endeavourto show below, <strong>the</strong>se species, however, run <strong>in</strong>to each o<strong>the</strong>r somuch that it is impossible to def<strong>in</strong>e <strong>the</strong> exact characters ofeach.S<strong>in</strong>ce I wrote my M<strong>on</strong>ograph 'of <strong>the</strong> K<strong>in</strong>gfishers,' our knowledgeof <strong>the</strong> great Laugh<strong>in</strong>g Jackasses of Australia has not been much<strong>in</strong>creased. The range of true Daceh has been extended to Sou<strong>the</strong>asternNew Gu<strong>in</strong>ea, where Dacelo <strong>in</strong>termed<strong>in</strong>s of Salvadori replacesD. cerv<strong>in</strong>us of <strong>the</strong> Australian c<strong>on</strong>t<strong>in</strong>ent; but o<strong>the</strong>rwise <strong>the</strong> numberof species <strong>in</strong> Australia has rema<strong>in</strong>ed <strong>the</strong> same as it was <strong>on</strong> <strong>the</strong> completi<strong>on</strong>of that work.A comparis<strong>on</strong>, however, of <strong>the</strong> large series of Laugh<strong>in</strong>g K<strong>in</strong>gfishersnow <strong>in</strong> <strong>the</strong> British Museum raises great doubts <strong>in</strong> my m<strong>in</strong>das to <strong>the</strong> validity of some of <strong>the</strong> species admitted by me up to 1871and I <strong>the</strong>refore add a few notes <strong>on</strong> <strong>the</strong> birds now before me.The chief difference between D. cerv<strong>in</strong>us and D. leacliii is supposedto c<strong>on</strong>sist <strong>in</strong> <strong>the</strong> smaller size, <strong>the</strong> buif-coloured breast, and <strong>the</strong> blueouter web of <strong>the</strong> external tail-fea<strong>the</strong>r of <strong>the</strong> former. It seems to menow that this last is a character of no value ; for it is evident that<strong>the</strong> young males commence with a rufous tail like <strong>the</strong> old females,and that <strong>the</strong>y ga<strong>in</strong> <strong>the</strong>ir blue tails by <strong>the</strong> gradual expansi<strong>on</strong> of <strong>the</strong>blue cross bands, which unite by degrees until <strong>the</strong> whole tail becomesuniform blue. Thus <strong>the</strong>re arrives a time <strong>in</strong> <strong>the</strong> development of <strong>the</strong>tail when <strong>the</strong> outer web of <strong>the</strong> tail-fea<strong>the</strong>r has not cjuite lost itsbars before becom<strong>in</strong>g uniform, and thus <strong>the</strong> barr<strong>in</strong>g of <strong>the</strong> tail, c<strong>on</strong>sideredto be a specific difference between D. cerv<strong>in</strong>us and D. leachii,is of very little importance. As regards <strong>the</strong> o<strong>the</strong>r characters, weshall see what <strong>the</strong>y are worth ; and <strong>in</strong> order to trace <strong>the</strong> developmentof <strong>the</strong> species, I add a descripti<strong>on</strong> of a young D. cerv<strong>in</strong>us :NestUnri. General colour above dark brown, with scarcely perceptiblelighter brown edges to <strong>the</strong> fea<strong>the</strong>rs of <strong>the</strong> mantle andscapulars ; least w<strong>in</strong>g-coverts brown like <strong>the</strong> back ; median andgreater series brown, tipped with pale verditer-blue or light greenishcobalt ; bastard-w<strong>in</strong>g brown, washed with blue ;primary-covertsblackish, externally greenish blue ;quills blackisb, externally deepblue, greener <strong>on</strong> <strong>the</strong> primaries, which are white near <strong>the</strong> bases ofboth webs ; <strong>the</strong> sec<strong>on</strong>daries edged with white at <strong>the</strong> tips, <strong>the</strong> <strong>in</strong>ner<strong>on</strong>es brown like <strong>the</strong> back ; lower back and rump pale silvery cobaltupper tail-coverts bright rufous, barred with black ; tail-fea<strong>the</strong>rsbright rufous, paler at <strong>the</strong> ends, barred with dark blue, <strong>the</strong>seblue bands marg<strong>in</strong>ed above and below with black, <strong>the</strong> bandsbroader near <strong>the</strong> base and narrower towards <strong>the</strong> ends ; <strong>the</strong> bluebands at <strong>the</strong> base of <strong>the</strong> middle fea<strong>the</strong>rs already coalesc<strong>in</strong>g <strong>in</strong>to <strong>on</strong>euniform blue base ; head nearly uniform dark brown, <strong>the</strong> fea<strong>the</strong>rsbroadly centred with blackish, <strong>the</strong> edges somewhat mottled withreddish-brown mark<strong>in</strong>gs ; <strong>the</strong> nape lighter, <strong>the</strong> crest- fea<strong>the</strong>rs be<strong>in</strong>gwhiter, with narrow dark-brown centres ; h<strong>in</strong>d neck clear fulvous,with more or less dist<strong>in</strong>ct zigzag cross l<strong>in</strong>es of brown ; lores tawnybuff, as also <strong>the</strong> fea<strong>the</strong>rs below <strong>the</strong> eye, <strong>the</strong> latter with blackish

BIRDS. 23shaft-streaks ; ear-coverts dusky brown ; cheeks clear fulvous, withcentral streaks of light brown, break<strong>in</strong>g up <strong>in</strong>to irregular cross l<strong>in</strong>es<strong>on</strong> some of <strong>the</strong> fea<strong>the</strong>rs ; throat and fore neck white, with irregularzigzag cross l<strong>in</strong>es of light brown ; rema<strong>in</strong>der of under surface of bodyunder tail-covertsclear fulvous, crossed with zigzag l<strong>in</strong>es of brown ;uniform and deeper buff ; axillarics like <strong>the</strong> breast and barred across<strong>in</strong> <strong>the</strong> same manner; under w<strong>in</strong>g-covcrts whiter and crossed dist<strong>in</strong>ctlywith blackish bars, broader and form<strong>in</strong>g a dist<strong>in</strong>ct patch <strong>on</strong> <strong>the</strong>median lower coverts near <strong>the</strong> edge of <strong>the</strong> w<strong>in</strong>g.The above descripti<strong>on</strong> is taken from a young male shot near PortEss<strong>in</strong>gt<strong>on</strong>.An old bird, with more than half his tail-fea<strong>the</strong>rs blue, has hisplumage very much abraded and <strong>the</strong> crest-fea<strong>the</strong>rs reduced tohair-like broAvn plumes. The blue ends to <strong>the</strong> w<strong>in</strong>g-coverts arealmost entirely worn off ; but <strong>on</strong> <strong>the</strong> breast he is replac<strong>in</strong>g hisfaded plumage by a clean moult, <strong>the</strong> new fea<strong>the</strong>rs be<strong>in</strong>g verybroadly centred with blackish ; <strong>the</strong> under surface of <strong>the</strong> body isdirty buff, with brown zigzag cross bars, becom<strong>in</strong>g less dist<strong>in</strong>ct <strong>on</strong><strong>the</strong> throat.Compared with young birds, <strong>the</strong> old D. cerv<strong>in</strong>a are very muchpaler buff below and less dist<strong>in</strong>ctly barred underneath, <strong>the</strong> collarround <strong>the</strong> h<strong>in</strong>d neck is nearly uniform, with scarcely any rema<strong>in</strong>sof zigzag cross-barr<strong>in</strong>g, while <strong>the</strong> head and crest are white orbuffy white, streaked with brown down <strong>the</strong> centre of <strong>the</strong> fea<strong>the</strong>rs ;but <strong>the</strong> whole head is dist<strong>in</strong>ctly streaked, <strong>in</strong>stead of be<strong>in</strong>g uniformbrown as <strong>in</strong> <strong>the</strong> young birds. The cobalt-blue <strong>on</strong> <strong>the</strong> shoulders is,of course, much more brilliant and more developed than <strong>in</strong> <strong>the</strong>young <strong>on</strong>es.The mode <strong>in</strong> which <strong>the</strong> barr<strong>in</strong>g <strong>on</strong> <strong>the</strong> under surface becomesless and <strong>the</strong> head more streaked is well shown <strong>in</strong> an immature malebird, which has <strong>the</strong> head los<strong>in</strong>g its uniformity for <strong>the</strong> streakedstage, and yet reta<strong>in</strong>s <strong>the</strong> rufous upper tail-coverts of <strong>the</strong> immaturestage, while <strong>the</strong> tail is <strong>on</strong>ly half overshaded with blue.The differences between <strong>the</strong> young and old specimens of Dacelocerv<strong>in</strong>us seem to me perfectly comprehensible ; but <strong>the</strong> relati<strong>on</strong>s ofD. leacMi and D. occidentalis are not so clear. There is c<strong>on</strong>siderablevariati<strong>on</strong> <strong>in</strong> length of w<strong>in</strong>g throughout <strong>the</strong> whole series.All our specimens of D. leachii have more or less rema<strong>in</strong>s of <strong>the</strong>irold rufous-barred tail, but <strong>the</strong>y are all complet<strong>in</strong>g <strong>the</strong>ir change to<strong>the</strong> uniform blue tail, and c<strong>on</strong>sequently <strong>the</strong> outer fea<strong>the</strong>rs are <strong>in</strong>more or less irregularly blue-banded stages ; but every proof is furnishedthat <strong>the</strong> outer fea<strong>the</strong>r will become perfectly blue, like <strong>the</strong>corresp<strong>on</strong>d<strong>in</strong>g stage <strong>in</strong> D. cerv<strong>in</strong>us, so that <strong>the</strong> character of <strong>the</strong> barredouter tail-fea<strong>the</strong>r will not hold.Undoubtedly D. leachii is a larger and more powerful bird thanD. cerv<strong>in</strong>us. It is often similarly fulvous <strong>on</strong> <strong>the</strong> breast ; but <strong>the</strong>zigzag bars are coarser and are c<strong>on</strong>t<strong>in</strong>ued higher up <strong>on</strong> <strong>the</strong> throat,as well as be<strong>in</strong>g str<strong>on</strong>gly developed <strong>on</strong> <strong>the</strong> collar round <strong>the</strong> h<strong>in</strong>dneck. The older <strong>the</strong> bird becomes, however, it is evident that, as <strong>in</strong>D. cerv<strong>in</strong>us, <strong>the</strong> cross-mark<strong>in</strong>gs <strong>on</strong> <strong>the</strong>se parts become more and more

24 COLLECTIONS FROM MELANESIA.obsolete, and <strong>the</strong>re is no difference between <strong>the</strong> two species except<strong>in</strong>g<strong>the</strong> hxrger size and whiter under surface of D. leacJiii.The types of D. oecidentalls from <strong>the</strong> Gould Collecti<strong>on</strong> are now<strong>in</strong> <strong>the</strong> Museum ; and for <strong>the</strong> same reas<strong>on</strong> that I dismissed <strong>the</strong>barred outer tail-fea<strong>the</strong>r as a character for separat<strong>in</strong>g Z>. leachii fromD. ccrv<strong>in</strong>vs, so I must refuse to c<strong>on</strong>sider it a mark of dist<strong>in</strong>cti<strong>on</strong>between D. cer^v<strong>in</strong>ns and D. occidentalis. The nearly uniform colorati<strong>on</strong>of <strong>the</strong> under surface is a much more peculiar feature ; but <strong>in</strong><strong>the</strong> female <strong>the</strong>re are some zigzag mark<strong>in</strong>gs <strong>on</strong> <strong>the</strong> flanks. That thisuniform under surface is somewhat accidental is proved by <strong>the</strong> factthat n<strong>on</strong>e of Dr. Elsey's specimens <strong>in</strong> <strong>the</strong> British Museum, procured<strong>in</strong> <strong>the</strong> same locality as Mr. Gregory's birds, are entirely withoutcross bars below.In <strong>the</strong> species from South-eastern New Gu<strong>in</strong>ea <strong>the</strong> appearance ofcross bars <strong>on</strong> <strong>the</strong> under surface seems to be <strong>the</strong> excepti<strong>on</strong> and not<strong>the</strong> rule, <strong>the</strong> collar round <strong>the</strong> h<strong>in</strong>d neck be<strong>in</strong>g also perfectly uniform.As with <strong>the</strong> Australian species, <strong>the</strong> cross bars are a sign ofimmaturity, be<strong>in</strong>g accompanied by a more uniform brown head.It would appear <strong>the</strong>refore, from a c<strong>on</strong>siderati<strong>on</strong> of <strong>the</strong> aboveseries, that not <strong>on</strong>e of <strong>the</strong> characters employed for <strong>the</strong> separati<strong>on</strong> of<strong>the</strong>se four Laugh<strong>in</strong>g K<strong>in</strong>gfishers is of permanent value. The barr<strong>in</strong>gof <strong>the</strong> tail-fea<strong>the</strong>rs must be set aside, be<strong>in</strong>g merely dependent up<strong>on</strong>age ; but tak<strong>in</strong>g D. cerv<strong>in</strong>us as <strong>the</strong> central form or lead<strong>in</strong>g type of<strong>the</strong> blue-tailed Jackasses of Australia, we f<strong>in</strong>d that eastwards (<strong>in</strong>Queensland) it varies to <strong>the</strong> extent of becom<strong>in</strong>g a larger bird, whiterunderneath, and always more or less barred <strong>on</strong> <strong>the</strong> under surface,<strong>the</strong> throat <strong>in</strong>cluded {D. leachii). In <strong>the</strong> western part of its range <strong>the</strong>bird has a tendency to become uniform underneath {D. occidentalis) ;but this may be due to <strong>the</strong> bleach<strong>in</strong>g effect of <strong>the</strong> climate, and it isevident that D. <strong>in</strong>termedius can <strong>on</strong>ly be looked up<strong>on</strong> as ano<strong>the</strong>r palerace, be<strong>in</strong>g led up to by <strong>the</strong> western specimens of D. cerv<strong>in</strong>us.49.

I cannot, however, agree with Try<strong>on</strong>that P. hippocastanum should also be classed with this species. Ishould here observe that <strong>the</strong> specimen figured by Eeeve as P. undataof Lamarck is unquesti<strong>on</strong>ably a variety of this species (bitubercularis),

MOLLUSC A. 51and appears to corresp<strong>on</strong>d with Kiener's idea of <strong>the</strong> Lamarckianshell (Coq.

But whe<strong>the</strong>r all or n<strong>on</strong>e of <strong>the</strong>sefigures del<strong>in</strong>eate <strong>the</strong> true P. undata appears to me questi<strong>on</strong>able.However, I do not believe that <strong>the</strong> West-Indian shell which hasbeen assigned to it by d'Orbigny (Eam<strong>on</strong> de la Sagra's Hist.

TheTrochoid form and flattened base of <strong>the</strong> species is not approached <strong>in</strong>that genus, and <strong>the</strong> character of <strong>the</strong> columella is very different.Accord<strong>in</strong>g to Mr. Tenis<strong>on</strong>-Woods <strong>the</strong>re is but <strong>on</strong>e species ot Risella<strong>in</strong> Australia (H. melanostoma of Gmel<strong>in</strong>), under which name he<strong>in</strong>cludes fifteen varieties or species, which have been named anddescribed by Lamarck, Quoy, Gray, Philippi, and o<strong>the</strong>rs.Although <strong>the</strong> separati<strong>on</strong> of many species or c<strong>on</strong>stant local formsseems impossible, we must not <strong>the</strong>refore ignore <strong>the</strong>ir existence.Riaella bruni is a South-Australian shell, and does not atta<strong>in</strong> anyth<strong>in</strong>g like <strong>the</strong> size of several of <strong>the</strong> o<strong>the</strong>r species, e. g. R. nana,R. mdanostoma, and R. imhricata. Although it might be possibleto get toge<strong>the</strong>r an immense series of specimens which would unitestep by step <strong>the</strong> two most extreme forms, never<strong>the</strong>less <strong>the</strong> R. hruniwould still rema<strong>in</strong> <strong>the</strong> small species from South Australia, and <strong>the</strong>o<strong>the</strong>r, <strong>the</strong> R. imhricata from Sydney, Port Stephens, &c., would alsobe recognizable as such.I am far from admitt<strong>in</strong>g <strong>the</strong> validity of all <strong>the</strong> described speciesbut <strong>the</strong>re are some, I th<strong>in</strong>k, which may be reta<strong>in</strong>ed, at all events,with c<strong>on</strong>v.'nience. It is not my <strong>in</strong>tenti<strong>on</strong> now to discuss this subjectfur<strong>the</strong>r, but, <strong>in</strong> c<strong>on</strong>clusi<strong>on</strong>, will call attenti<strong>on</strong> to Philippi's m<strong>on</strong>ographof <strong>the</strong> genus, w^hich has been altoge<strong>the</strong>r overlooked by Crosse(Journ. de C<strong>on</strong>ch. 1864) aud by Tenis<strong>on</strong>-Woods ; it was published<strong>in</strong> 1853 <strong>in</strong> Kiister's C<strong>on</strong>chylien-Cab<strong>in</strong>et,' and 'c<strong>on</strong>ta<strong>in</strong>s <strong>the</strong> follow<strong>in</strong>g

Ano<strong>the</strong>r species whichhas also escaped attenti<strong>on</strong> is <strong>the</strong> Trochus melanostoma of Reeve(Proc. Zool. Soc. 1842, p. 185 ; C<strong>on</strong>ch. Sjst. vol. ii. pi. 218. fig. IG).This is <strong>the</strong> same as RiseJla fimbriata of Philippi, which I th<strong>in</strong>kshould be regarded as a large form of R. melanostoma, Gmel<strong>in</strong> ;andwith this species I would also unite R. fiavescens and R. pUcatida ofPhilippi. Dunker has also described a species from Sydney under<strong>the</strong> name of R. crassa, which appears to be remarkable <strong>on</strong> accountof a thickened channelled lip (Mai. Bliit. 1861, vol. viii. p. 42).R. Jcielmannseggl, Zelebor, is <strong>the</strong> R. lutea, Quoy, of which R.imbricata may be a variety. The two follow<strong>in</strong>g species resembleRisella <strong>in</strong> form, but have <strong>the</strong> c<strong>on</strong>centric multispiral operculumof Ti'ocJms, from which <strong>the</strong>y are dist<strong>in</strong>guished by <strong>the</strong>ir n<strong>on</strong>-pearlyapertures Trochus tantillus, Gould, and Risclla isseli, Semper.The Tectarhis luteus of Gould, Risella <strong>in</strong>fracostata, Issel, R. parvula,Dunker (?= tantillus), and Trochus c<strong>on</strong>oidaUs of Pease willprobably have similar opercula ;<strong>the</strong>se four species differ fromRisella not <strong>on</strong>ly <strong>in</strong> <strong>the</strong> operculum, but <strong>in</strong> be<strong>in</strong>g narrowly perforated.The statement with regard to Risella aurata be<strong>in</strong>g <strong>the</strong>male of R. nana (although both are hermaphrodite) <strong>made</strong> byMr. Tenis<strong>on</strong>-Woods (Proc. L<strong>in</strong>n, Soc. N. S. Wales, vol. i. p. 244),and that " cdl breed freely with <strong>on</strong>e ano<strong>the</strong>r," seems to me to requiresome fur<strong>the</strong>r corroborati<strong>on</strong>. He himself hesitates to assertpositively that ei<strong>the</strong>r of <strong>the</strong>se two forms are <strong>in</strong>capable of reproduc<strong>in</strong>g<strong>the</strong>ir own k<strong>in</strong>d, " for <strong>the</strong>re are many places <strong>on</strong> <strong>the</strong> coastwhere no species can be found except <strong>the</strong> variety now known asR. aurata." This, <strong>in</strong> my judgment, proves that that species at allevents is self-propagat<strong>in</strong>g ;yet Mr. Tenis<strong>on</strong>-Woods says thatspecimens of this species kept <strong>in</strong> glass jars for a few weeks did notbecome fertile.

Zuol. 1845, Zooph. p. 21, pi. 10.Liuckia marmorata, Perrier, p. 13o.If I am correct <strong>in</strong> referr<strong>in</strong>g to this species a series of specimensfrom Port Molle and Fitzroy Island, it will be easy to understandhow it is that M. Michel<strong>in</strong>'s species was never aga<strong>in</strong> recognized till<strong>the</strong> Paris Museum came <strong>in</strong>to <strong>the</strong> possessi<strong>on</strong> of his type ; that wouldappear to be <strong>the</strong> <strong>on</strong>ly example that <strong>the</strong>y possess, and, as M. Perrierpo<strong>in</strong>ts out, <strong>the</strong> " typo " is obviously young. The specimens beforeme are clearly enough all representatives of <strong>the</strong> same species ; butwere any <strong>on</strong>e of <strong>the</strong>m described it is quite possible that from <strong>the</strong>descripti<strong>on</strong> al<strong>on</strong>e of that s<strong>in</strong>gle specimen it would be easy to regardsome o<strong>the</strong>rs of <strong>the</strong> series as bel<strong>on</strong>g<strong>in</strong>g to ano<strong>the</strong>r form.In <strong>the</strong> first place, though all <strong>the</strong> specimens are provided with <strong>the</strong><strong>in</strong>termediate plate that c<strong>on</strong>nects <strong>in</strong>to a pentag<strong>on</strong> <strong>the</strong> term<strong>in</strong>al <strong>on</strong>e of<strong>the</strong> " ranges de plaques qui occupe la ligne mediane dorsale dechaque bras," <strong>the</strong> extent to which this is evident varies a good deal,and <strong>on</strong>e would hardly th<strong>in</strong>k it worthy of especial note <strong>in</strong> <strong>the</strong> largestexample were not attenti<strong>on</strong> directed to it by <strong>the</strong> better-markedcharacters of some of <strong>the</strong> smaller. Sec<strong>on</strong>dly, <strong>the</strong> smallest specimenhas <strong>the</strong> dorsal plates covered with coarse granulati<strong>on</strong>s ; of some of<strong>the</strong>se, at any rate, it would be appropriate to say (aga<strong>in</strong> quot<strong>in</strong>gPerrier) " les granules vois<strong>in</strong>s de leur centre sent un peu plus grosque les autres;" <strong>on</strong> <strong>the</strong> o<strong>the</strong>r hand, <strong>on</strong>e, two, or more granulesnear <strong>the</strong> centre acquire, <strong>in</strong> <strong>the</strong> larger specimens, a much greaterpredom<strong>in</strong>ance, and give a somewhat different appearance to <strong>the</strong>creature ;<strong>in</strong> <strong>the</strong> largest specimen <strong>the</strong>se aga<strong>in</strong> have disappeared, and<strong>the</strong> whole surface of <strong>the</strong> plates is more uniformly granular. Thirdly,<strong>the</strong> dorsal plates may lose <strong>the</strong> regularity of outl<strong>in</strong>e which is so wellmarked (if not exaggerated ?) <strong>in</strong> Michel<strong>in</strong>'s figure, and which isexpressed by M. Perrier <strong>in</strong> <strong>the</strong> words " sensiblement carree," andbecome narrower at <strong>the</strong> angles at which <strong>the</strong> pores are placed ; thisis perhaps due to <strong>the</strong> greater development <strong>in</strong> <strong>the</strong> number of pores,of which as many as seven may <strong>in</strong> some cases be found with<strong>in</strong> <strong>the</strong>limits of <strong>on</strong>e area. Lastly, it is <strong>on</strong>ly <strong>in</strong> <strong>the</strong> smallest specimens thatwe f<strong>in</strong>d a double row of tubercles fr<strong>in</strong>g<strong>in</strong>g <strong>the</strong> adambulacral sp<strong>in</strong>es ;<strong>in</strong> aU <strong>the</strong> larger specimens <strong>the</strong> row is s<strong>in</strong>gle, or, <strong>in</strong> o<strong>the</strong>r words, <strong>on</strong>erow of tubercles ceases to grow proporti<strong>on</strong>ately, and becomes obscured<strong>in</strong> <strong>the</strong> general granulati<strong>on</strong> of <strong>the</strong> act<strong>in</strong>al surface.The <strong>on</strong>ly c<strong>on</strong>siderable po<strong>in</strong>t of difference between <strong>the</strong>se specimensand that figured by Michel<strong>in</strong> lies <strong>in</strong> <strong>the</strong> remarkable colorati<strong>on</strong> ofhis specimen ; if, however, M. Desjard<strong>in</strong>'s example from <strong>the</strong> islandof Mauritius was immediately dried, it might have reta<strong>in</strong>ed its colour :while Dr. Copp<strong>in</strong>ger's specimens, which were placed <strong>in</strong> spirit, mightvery possibly have had part of <strong>the</strong>ir colour<strong>in</strong>g-matter dissolved out.The largest example has E equal to 50 miUim.Pr<strong>in</strong>ce of Wales Channel, 7 fms.

The orig<strong>in</strong>al specimens,collected by Prof. Semper <strong>in</strong> <strong>the</strong> Philipp<strong>in</strong>es, were describedby Mr. Lyman as be<strong>in</strong>g <strong>in</strong> colour, " above, bright <strong>in</strong>digo, with adarker l<strong>in</strong>e al<strong>on</strong>g <strong>the</strong> arm, bounded by a lighter <strong>on</strong>e <strong>on</strong> ei<strong>the</strong>r side ;below, paler <strong>in</strong>digo, with a white l<strong>in</strong>e al<strong>on</strong>g <strong>the</strong> arm."

In <strong>the</strong>two specimens collected <strong>on</strong> "Aug. 7, 1874" (<strong>in</strong> <strong>the</strong> neighbourhoodof <strong>the</strong> Fiji Islands), by <strong>the</strong> ' Challenger,' and determ<strong>in</strong>ed by Mr.Lyman, I observe that <strong>the</strong>re is a fa<strong>in</strong>t <strong>in</strong>dicati<strong>on</strong> of a white l<strong>in</strong>e <strong>on</strong>ei<strong>the</strong>r side of <strong>the</strong> blue l<strong>in</strong>es <strong>on</strong> <strong>the</strong> disk, and that <strong>the</strong> white l<strong>in</strong>e<strong>on</strong> <strong>the</strong> ventral surface is, at places, broken across by a patch of<strong>in</strong>digo.On ei<strong>the</strong>r side of <strong>the</strong>se " typical specimens " <strong>the</strong>re would appearto be a light and a dark variety. In <strong>the</strong> latter <strong>the</strong> whole creaturemay be deep purple, <strong>the</strong> two white l<strong>in</strong>es <strong>on</strong> <strong>the</strong> arms be<strong>in</strong>g at regulardistances <strong>in</strong>vaded by purple patches of such a size as to leave <strong>on</strong>lyspaces of white equal to <strong>the</strong>mselves ; and as <strong>the</strong>se patches are symmetrical<strong>on</strong> ei<strong>the</strong>r side of <strong>the</strong> middle l<strong>in</strong>e, <strong>the</strong> orig<strong>in</strong>al white l<strong>in</strong>escome to be represented by noth<strong>in</strong>g more than paired patches of white ;similarly <strong>the</strong> white l<strong>in</strong>e below disappears, or ra<strong>the</strong>r is forced out to<strong>the</strong> sides, and appears <strong>on</strong>ly as a th<strong>in</strong> marg<strong>in</strong>al l<strong>in</strong>e.

ECHTNODERMATA. 1 53CRINOIDEA.In <strong>the</strong> preparati<strong>on</strong> of this porti<strong>on</strong> of my <str<strong>on</strong>g>Report</str<strong>on</strong>g> I have had <strong>the</strong>very c<strong>on</strong>siderable advantage of <strong>the</strong> k<strong>in</strong>dness of Mr. P. Herbert Carpenter,whose work <strong>on</strong> this group is so well known to, and so highlyappreciated by, his fellow-workers. Mr. Carpenter has not <strong>on</strong>lybeen good enough to favour me with his op<strong>in</strong>i<strong>on</strong> <strong>on</strong> many of <strong>the</strong>species and specimens <strong>in</strong> <strong>the</strong> preseut collecti<strong>on</strong>, but, at what musthave been c<strong>on</strong>siderable trouble to himself, he copied out for me<strong>the</strong> notes that he had been able to make at various times andplaces <strong>on</strong> <strong>the</strong> " type specimens " of <strong>the</strong> species named by <strong>the</strong> illustriousfounder of <strong>the</strong> system of this group ; thanks to this act ofk<strong>in</strong>dness, I have probably escaped from some of <strong>the</strong> numerous pitfallswhich, with <strong>the</strong> advance of our knowledge, now surround <strong>the</strong> studentwho applies himself to Johannes Miiller's descripti<strong>on</strong>s of <strong>the</strong> differentspecies. As Mr. Carpenter will, <strong>in</strong> <strong>the</strong> progress of time, publishhis studies <strong>on</strong> <strong>the</strong>se Miillerian types, I have thought it proper <strong>on</strong>this occasi<strong>on</strong> to do little more than merely note <strong>the</strong> presence of suchforms <strong>in</strong> this collecti<strong>on</strong>.The proporti<strong>on</strong> of undescribed to described species is no doubtappall<strong>in</strong>g ; but <strong>on</strong> mak<strong>in</strong>g a careful estimate I do not f<strong>in</strong>d it to bepractically greater than <strong>in</strong> <strong>the</strong> case of my predecessors. In a Notewhich I communicated to <strong>the</strong> Zoological Society <strong>in</strong> May 1882 I gavea list of all <strong>the</strong> described species, which was very nearly complete :<strong>the</strong>re<strong>in</strong> were enumerated 37 Anted<strong>on</strong>s and 21 Actmometne. Of<strong>the</strong>se, 7 Anted<strong>on</strong>s and 4 Act<strong>in</strong>ometrce were first described <strong>in</strong> 1881,from <strong>the</strong> collecti<strong>on</strong> of <strong>the</strong> Leyden Museum, by Mr. Carpenter. Inthat paper <strong>the</strong> percentages of new to all <strong>the</strong> known species wererespectively 23 and 23 ; <strong>the</strong> percentages to new species <strong>in</strong> <strong>the</strong> collecti<strong>on</strong>respectively 70 and 40.As <strong>the</strong>re are here described 12 new species of Anted<strong>on</strong>^ my percentageto <strong>the</strong> 37 described forms is 32-5, to all <strong>the</strong> species menti<strong>on</strong>ed<strong>in</strong> this Eeport it is 75 ; <strong>on</strong> <strong>the</strong> o<strong>the</strong>r hand, <strong>the</strong>re are some 5new species of Act<strong>in</strong>ometra, giv<strong>in</strong>g a percentage of 23*5 to all <strong>the</strong>described forms, and of 38 to those enumerated <strong>in</strong> <strong>the</strong> accompany<strong>in</strong>gUst.Aga<strong>in</strong>st this higher proporti<strong>on</strong> we must, however, set off <strong>the</strong> factthat five of <strong>the</strong> earlier species had been described by Miiller from<strong>the</strong> specimens <strong>in</strong> <strong>the</strong> Leyden Museum.But <strong>the</strong> whole story has not yet been told : withovit, of course,want<strong>in</strong>g <strong>in</strong> any way to tie Mr. Carpenter down to details, I may addthat his exam<strong>in</strong>ati<strong>on</strong> of <strong>the</strong> 'Alert' collecti<strong>on</strong> was <strong>made</strong> after he hadexam<strong>in</strong>ed <strong>the</strong> collecti<strong>on</strong> of Cr<strong>in</strong>oids brought toge<strong>the</strong>r by <strong>the</strong> officersof H.M.S. ' Challenger,' and entrusted to him for descripti<strong>on</strong>. Onlya s<strong>in</strong>gle form am<strong>on</strong>g <strong>the</strong> "new species" <strong>in</strong> <strong>the</strong> present collecti<strong>on</strong>has been detected by Mr. Carpenter to be <strong>on</strong>e of <strong>the</strong> treasures whichhe has described, but whose descripti<strong>on</strong> he has not yet published ;

When, however, we make a careful comparis<strong>on</strong>between <strong>the</strong> pattern of this colorati<strong>on</strong> and that of <strong>the</strong> two specimensfirst described and unhesitat<strong>in</strong>gly referred to A. Solaris, wesee that <strong>the</strong>re is really a strik<strong>in</strong>g resemblance between <strong>the</strong> two, andwe are aga<strong>in</strong> led to <strong>the</strong> reflecti<strong>on</strong> that great circumspecti<strong>on</strong> is to beexercised whensoever we are tempted to make use of difference <strong>in</strong>colour as a dist<strong>in</strong>guish<strong>in</strong>g mark. I have already stated that <strong>the</strong>reare black patches or spots <strong>on</strong> <strong>the</strong> p<strong>in</strong>nules of <strong>the</strong> first-described pair ofspecitueus ; what we f<strong>in</strong>d <strong>in</strong> <strong>the</strong> <strong>on</strong>e now under c<strong>on</strong>siderati<strong>on</strong> is that<strong>the</strong>se spots hav<strong>in</strong>g greatly <strong>in</strong>creased <strong>in</strong> number, and become more extensivethan <strong>the</strong> white, have caused <strong>the</strong> white ground to assume <strong>the</strong>appearance of spots <strong>on</strong> a dark ground. The extreme limit of <strong>the</strong>species seems, however, to be reached by this form ; and as <strong>the</strong> cirriare more numerous than usual, and <strong>the</strong> basal jo<strong>in</strong>ts of <strong>the</strong> sec<strong>on</strong>dp<strong>in</strong>nule less str<strong>on</strong>gly keeled, I propose to speak of it as A.

Australia, Pentagoyiaster dubeni from S.Australia, and Tosia austraUs from S. Australia and Tasmaniawhile <strong>the</strong> present collecti<strong>on</strong> enlarges <strong>the</strong> range of Patiria crassa.Although <strong>the</strong>re appeared at <strong>on</strong>e time to be good reas<strong>on</strong> for disagree<strong>in</strong>gwith Mart<strong>in</strong>t, <strong>the</strong> present amount and weight of evidence<strong>in</strong> our hands goes to po<strong>in</strong>t to <strong>the</strong> existence of a tropical oceanicfauna ; to-day, as <strong>in</strong> those Tei'tiary times when a wider sea separated<strong>the</strong> Australian from <strong>the</strong> Asiatic c<strong>on</strong>t<strong>in</strong>ent, <strong>the</strong>re are forms whosebreadth of range is co<strong>in</strong>cident ra<strong>the</strong>r with iso<strong>the</strong>rmal l<strong>in</strong>es thantopographical boundaries.For <strong>the</strong> elucidati<strong>on</strong> of <strong>the</strong> details of this tropical fauna, we maylook with almost more than c<strong>on</strong>fidence to <strong>the</strong> <strong>in</strong>formati<strong>on</strong> affordedby <strong>the</strong> species of Cr<strong>in</strong>oids : here, however, <strong>the</strong> cab<strong>in</strong>et naturalist canas yet <strong>on</strong>ly appeal to <strong>the</strong> collector.* Evidence as to this was given by <strong>the</strong> earlier collecti<strong>on</strong>s of <strong>the</strong> 'Alert' <strong>in</strong><strong>the</strong> Straits of Magellan (see P.
