CRUSTACEA. 52920. Atergatopsis granulatus, A. M.-Edw.A small female from Marie-Louise Island, 17 fms. (Xo. 18G),belongs, I think, to this species. It has the carapace uniformlygranulated, as in A. Milne-Edwards's figure, based on specimensfrom Zanzibar.The specimens in. the British Museum (from the collection ofH.M.S. 'Samarang') designated by A. M.-Edwards A. granulatusare without special indication of locality ; they differ from his description,and resemble (as it would appear)^, lucasii, in having thecarapace granulated only towards the antero-lateral margins ; butthey have the strong compressed tooth on the lower (immobile)finger, which is deficient in A. Jucasi, but exists in A. gramdatus.They seem therefore to be intermediate between the two species ;but a larger series of the genus is needed to show whether or nothey should be regarded as specifically distinct.21. Xantliodes lamarckii {M.-Edw.).Darros Island, beach (No. 200); a small male and two females.Specimens are in the British-Museum collection from Madagascar,Tamatave {Rev. Deans Coivan) ; Ce3lon, Galle (Dr. W. Ondaatje) ;Philippines (Cuming) ; and Eastern Seas, without special locality(11.21. StS. ''Samarang' and ^Herald'). It is distributed throughoutthe Oriental liegion eastward to the Pacific islands, since A. Milne-Edwards records it from New Caledonia.22. Carpilodes rugatus (M.-Edw.).Seychelles, 4-12 fms. (No. 194) ; an adult female.Specimens are in the British-Museum collection from the RedSea, Daedalus Shoal (Lt.-Gol. Flayfair), and Galle, Ceylon (Dr. W.Ondaatje).This species is widely distributed throughout the Oriental Region;it has been recorded from various localities eastward to New Caledonia.Specimens which are referred doubtfully to the nearly allied, but,as I think, distinct, C. vadlantianus (A. M.-Edwards*), are in theBritish-Museum collection from the Seychelles (Dr. E. P. Wright).In these specimens the lobes of the carapace are less prominent thanin C. rugatus, and the sulci of the branchial regions are shorter,not prolonged to those which define the cardiac region of thecarapace.* Auuexe F, Crustacea, p. 3, in Maillard, ' Ilo Euunion' (1SG2).2m
