CEUSTACEA. 529 



20. Atergatopsis granulatus, A. M.-Edw. 



A small female from Marie-Louise Island, 17 fms. (JSo. 186), 

 belongs, I think, to this species. It has the carapace uniformly 

 granulated, as in A. MUne-Edwards's figure, based on specimens 

 from Zanzibar. 



The specimens in the British Museum (from the collection of 

 H.M.S. ' Samarang ') designated by A. M.-Edwards A. granulatus 

 are without special indication of locality ; they differ from his de- 

 scription, and resemble (as it would appear) A. lucasii, in having the 

 carapace granulated only towards the antero-lateral margins ; but 

 they have the strong compressed tooth on the lower (immobile) 

 finger, which is deficient in A. lueasi, but exists in A. granulatus. 

 They seem therefore to be intermediate between the two species ; 

 but a larger series of the genus is needed to show whether or no 

 they should be regarded as specifically distinct. 



21, Xanthodes lainarckii (M.-Edw.). 



Darros Island, beach (No. 200) ; a small male and two females. 



Specimens are in the British-Museum collection from Madagascar, 

 Tamatave (Bev. jyecms Cowan) ; Ceylon, Galle {Dr. W. Ondaatje) ; 

 Philippines (Ouming) ; and Eastern Seas, without special locality 

 (H.M.SS. ' Samarang ' and ' Herald '). It is distributed throughout 

 the Oriental Eegion 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 Eed 

 Sea, Daedalus Shoal {Lt.-Col. Playfair), and Galle, Ceylon {Dr. W. 

 Ondaatje). 



This species is widely distributed throughout the Oriental Eegion; 

 it has been recorded from various localities eastward to New Cale- 

 donia. 



Specimens which are referred doubtfully to the nearly allied, but, 

 as I think, distinct, C. vaillantianus (A. M.-Edwards*), are in the 

 British-Museum collection from the Seychelles {Dr. E. P. Wright). 

 In these specimens the lobes of the carapace are less prominent than 

 in C rugatus, and the sulci of the branchial regions are shorter, 

 not prolonged to those which define the cardiac region of the 

 carapace.
