Report on the zoological collections made in the Indo-Pacific Ocean ...

200 COLLECTIONS FROM MELANESIA.In the second collection are two males and a female from ThursdajrIsland, 3-4 fms. (No. 175), and a small female obtained on the beachat Port Darwin (No. 176).Nearly all of these specimens present the rostral charactersattribnted by Haswell to his L. spinifei% but in one example of theseries the lateral teeth of the rostrum are absent. Traces of them,as very obscure tubercles, exist in tbe typical examples of L. longispinusin the British-Museum collection.In some of the specimens the spines of the cardiac and branchialregions and of the posterior and postero-lateral margins are muchmore strongly developed than in others. Besides the above mentionedAustralian localities, Mr. Haswell records this species fromDarnlejf Island, and Cape Grenville.23. Lamhrus laevicarpus, Miers.Two small males are in Dr. Coppinger's second collection, obtainedin the Arafura Sea off the N.W. coast of Australia at a depth of32-36 fms. (No. 160). They agree in all particulars with thetypical specimen, without definite locality, in the Museum collection.24. Lambrus longimanus {Linn.).To this species as I have defined it ('Annals', xix. p. 21, 1879)are to be referred an adult male specimen from Flinders, Clairraont,obtained at a depth of 11 fms. (No. 108) ; a male and a female fromPort Molle, 14 fms. (No. 93) ; and a female of large size, with ova,from Fitzroy Island, 10 fms. (No. 113).This species, as I have already noted, ranges from the Mauritiusthrough the Indian and Malaysian seas to the North-easterncoast of Australia.25. Lambrus nodosns (Jacquinot and Lucas).A small male in the first collection from Port Denison, 4 fms.(No. 122), belongs here. Specimens from the same locality arerecorded by Mr. Haswell, the original types being from New Zealand.In the second collection are a male and a female from ThursdayIsland, 3-4 fms. (Nos. 175-177).Small specimens of this species have a considerable resemblanceto the L. intennedius, described by myself from the Corean seas*,where also are perhaps to be referred small specimens fromShark Bay, W. Australia {Rwjner, H.M.S. 'Herald'), in the British-Museum collection, from which L. nodosus is distinguished by theprominent and globoscly-rounded tubercles of the chelipedes. InL. intermedius the marginal tubercles of the chelipedes are flattenedand (in the typical specimen) tlio palms are quite smooth ontheir upper surfaces. Very small granules exist, however, on the* Proc. Zool. Soc. p. 30 (1879).
