CRUSTACEA.. 257without locality, and being also of very small size, I was uncertain,whether to regard them as belonging at all to this genus, andif so, whether they might not represent an immature condition ofone of the known species. This, I am inclined to think, cannot bepossible, since there are one or two Matatce in the collection noku'ger than M. inennis, in which nevertheless the lateral spines aredistinctly developed and the carapace of the normal width. Inthe obsolescence of the lateral spines 31. inennis resembles the genusCryptosoma ; but in the form of the chelipedes and of the dactyli ofthe swimming-legs and in the mouth-organs it is altogether a Matuta.113. Calappa hepatica (Linn.).An adult male was obtained near Clairmont on a coral-reef(No. 151).Specimens are in the British-Museum collection from the followingAustralian localities Trinity Bay, N.E. Australia (J. Macgillivray,H.M.S. Eattlesnake ' '), also from Bramble Key and West Hill {J.B. Jul-es). Hess records it from Sydney.I have already * referred to the extended geographical range ofthis common species, which is more generally known by Fabricius'sdesignation C. tiiberculata.114.

Crust, p. 137;(1882).To this species are referred a male from Port Molle, 14 fms. (No.93) ; another from Port Denison, 4 fms. ; a female from Flinders,Clairmont, N.E. Australia, 11 fms. ; and a small male in very imperfectcondition from Thursday Island, 4-6 fms. (No. 130), inwhich the carapace is narrower than usual. All of the above from thefirst collection. In the second collection, three small specimens fromthe Arafura Sea, 32-36 fms. (No. 160), probably belong here.Another very small example from Friday Island, 10 fms. (No. 153),which has the carapace glabrous, but tuberculatcd nearly as in D.dorsipes, I cannot assign with certainty to any species.* Phil. Trans, clxviii. p. 491 (1879).
