Numerous specimens — adults and young of both sexes — from the 

 Andamans. 



Ipkiculus, Adams and White.

The whole body and its appendages, except only the fingers, covered 

 with a dense spongy or woolly tomentum, beneath which, when denu- 

 ded, the surface is rough granulons or pustulous, and beneath which the 

 regions of the carapace — especially the cardiac and intestinal — are de- 

 marcated by grooves. 



Carapace transversely somewhat oval, its lateral margins spinate. 



The front is narrow and is sunk behind the level of the edge of the 

 buccal cavern, and appears still more sunken because the hepatic and 

 sub-hepatic regions are puffed out beyond it at the sides and in front. 



The orbits are obliquely elongate and completely conceal the eyes, 

 in the denuded carapace three sutures can be made out in the emargin- 

 ate roof. There is a gap at the inner canthus in which stands the basal 

 joint of the antenna, the largish nagellum of which appears to be inside 

 the orbit. The antennules fold very obliquely. There is a broad 

 vertical space between the lower edge of the orbit, and the edge of the 

 buccal cavern. 



The buccal cavern is triangular : the merus of the external max- 

 illipeds is half the length of the ischium measured along the inner 

 border. 



The chelipeds are about If the length of the carapace : the hand 

 is short and globular : the fingers are slender and hook -like, much 

 longer than the hand, and open in a somewhat oblique plane, the tip of 

 the mobile finger moving easily through an arc of 120°. Legs rather 

 large. 



Abdomen of male with the 3rd and 4th segments fused : that of 

 the female with all the segments distinct.

Carapace convex, transversely ovoidal, much broader than long, 

 the surface when denuded of its woolly covering granulous with numer- 

 ous larger pustulous tubercles, and showing the cardiac and intestinal 

 regions tumid and very well demarcated by grooves. On the antero- 

 lateral margins are four large coarse close spines, increasing in size from 

 before backwards ; on the postero-lateral margins are two coai'se denti- 

 form tubercles separated by a wide interval.
