Curcinoloyical Fauna of hulia. 363 



pair of legs are, even in the male, decidedly shortened and foHaceous 

 joints. 



On the other liand the fiont is, as in G. Dicssumieri, extremely 

 narrow, and its bevelled and moulded edges take up most of its breadth 

 between the eye-stalks. IHie regions of the carapace, also, are as 

 strongly defined as they are in O. Dussumifri. 



Tlie large hand of the male resembles that of G. Dussuniieri in 

 having both the oblique gi'anular indges on the inner sniface of the 

 palm strongly salient, and in having very long fingers with simple 

 hooked tips : the fingers however are not so broad and thin, and the 

 lobe near the middle of the dentary edge of tlie immobile finger may 

 be present or not. 



In the Indian Museum are 10 specimens, from Karachi, Madras, 

 and the Nicobars. 



The carapace of the largest specimen is 20 millim. long and 36 

 millim. broad.

Cephalothorax so deep as to be subcubical, as long as broad or a 

 little broader than long. Anteriorly the sidewalls of the carapace have 

 a curious gyrous-sulcate sculpture resembling brain-convolutions: often 

 also a similar kind of sculpture is found on the dorsum of the carapace 

 and on the meropodites of the external maxillipeds. 



Fiont a narrow deflexed lobe much as in Ocypoda. Tiie orbits, 

 which occupy all the rest of the anterior border of the carapace, are 

 more or less oblique and shallow — in one species so shallow as to be 

 almost obsolete. Eyestalks rather long and slender, Avith the eyes at 

 the end. 



Antennules, like those of Ocypoiht, having the basal joint of good 

 size, and the flagellura small and hidden by the front. The antenna? 

 stand at the inner angle of the lower orbital border and have a rather 

 short flagellum. 



The epistome would be linear but for a large median tiiangular 

 lobe that projects between the external maxillipeds. 



Buccal cavern enormous, suboval or suboircular in outline : the 

 external maxillipeds, which completely cover it and are also very large, 

 have a strong almost heniisphcrical bulge ; their merus is much larger
