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

CRUSTACEA. 179contains not only the results of his own previous researches on theAustralian Stalk- and Sessile-eyed Crustacea (which are to be foundin a series of papers communicated to the Linnean Society of XewSouth Wales *, wherein a very considerable number of species newto science are described and illustrated), but also gathers into a formconvenient for reference nearly all the work of earlier authors—notmerely what is contained in the special memoirs referred to above,but also the numerous Australian species described and incidentallynoticed in the publications of A. Whice, Spence Bate, A, Milne-Edwards, and others, or in my own papers.In this Catalogue no fewer than 54U species of Podophthalmiousand Edriophthalmious Crustacea are described ; but, large as thisnumber may appear, it is necessarily very far from being a completeenumeration of the Stalk- and Sessile-eyed Crustacea of this greatcontinent, which presents in its different regions such diverse conditionsof temperature and climate. This will appear from thelarge number of species described in the following pages, which areeither new to science or not included in the ' Catalogue ' ; and Imay add that, had time and opportunity allowed, it would havebeen possible to largely add to the, list of unrecorded Australianspecies from the rich material accumulated in the National Collectionalone.In the present memoir 203 species and well-marked varieties o-fCrustacea and Pycnogonida are enumerated from the Australianseas, besides several which are described or incidentally referred to,but which do not belong to the Australian fauna. Forty-five newor undescribed species and ten varieties are described for the firsttime ; while of the total number (193 in all) of species and varietiesof Australian Podophthalmia and Edriophtbalmia noticed in thefollowing pages, ninety-six arc not included in Mr. Haswell's catalogue.Among the species described as new are several to whichWhite applied specific names but never characterized ; these nameshave been, of course, adopted. Besides the new species, severalhitherto very imperfectly known from the existing descriptions (andtherefore only to be identified with some uncertainty) have beenredescribed and illustrated.Geof/rcqjhical Distribution.—As regards the geographical range ofthe species, I have not thought it necessary (nor, indeed, would itbe possible within the limits of this lleport) to give all the hithertorecorded localities, many of them being common and widely-rangingOriental forms which occur (or may occur) on every coast-lin©within the wide Indo-Pacific or Oriental region. Full particulars^however, are given of the Australian localities, and many are nowfor the first time recorded on the authority of specimens in theBritish-Museum collection obtained by the naturalists of H.M.SS.'Rattlesnake' and 'Herald,' and by the late Messrs. Dring, J. B.Jukes, and other gentlemen, by whose zeal and discriminationour National Collection has so greatly benefited. In the case* Journal of the Linnean Society of N. S. Wales, iii.-vi.
