ALLAN HANCOCK PACIFIC EXPEDITIONS 



VOL. 5 



Fig. 15. Pseudosquilla oculata, male, from Gardner Bay, Hood 

 Island, Galapagos (Hancock Exped. Sta. 30-33, February 26, 

 1933). a. telson and left uropod; b. rostral plate. 



Distribution : A widely distributed species. Atlantic Ocean: Canary 

 Islands, Madeira, Cape Verde Islands, and Maceio, Alagoas, Brazil. 

 Indian Ocean: Chagos Islands and Mauritius. Pacific Ocean: Bonin 

 Islands, China Sea (Macclesfield Bank), Gilbert Islands, Laysan, Ha- 

 waiian Islands, Samoa, Society Islands, Clarion Island (Mexico) (Rath- 

 bun, Kemp, Edmondson, Bigelow). 



To the foregoing Pacific localities may be added the Tres Marias 

 Islands, Mexico, from which a single female was obtained by Dr. Carlos 

 Stansch, of the Direccion Forestal y de Caza y Pesca, in 1927, and a 

 number of specimens taken by the Hancock Expeditions on the Pacific 

 coast of the Republic of Panama and Colombia and in the Galapagos 

 Islands. 



Size: Most of the specimens in the collection are quite small, but 

 there is one large female from Osborn Island in Gardner Bay, Hood 

 Island (Sta. 30-32), which appears to be the largest known representative 

 of the species. In median length inclusive of the rostral plate, it is about 

 86.5 mm. long, the carapace measures 17.1, the rostral plate 3%; if 

 measured over the movable submedian spines, the total length would 

 approach 89 mm. As far as I have been able to ascertain, the next speci- 

 men in point of size is that seen by Miers^^ in the British Museum. It is 

 also a female, and measures "3^ inches in length" (not quite 83 mm.).
