Geographical range : from tropical east Africa to Tahiti: also, according 

 to Bouvier, tropical west Africa. 



Ccenobita clypeatus grows to a large size, and sometimes finds difficulty 

 m fitting itself with a shell. Other observers, besides myself, have seen it 

 using the half of a coconut shell ; and I once, at Minnikoy, saw a very large 

 individual going about without protection of any sort.

Carapace punctate behind, punctate and granulous in front of the cer- 

 vical groove, the gastric region hardly at all convex. 



Eyestalks compressed, reaching beyond the middle of the terminal joint 

 of the antennal peduncle, dorsally scabrous. Ophthalmic scales narrow, 

 sharply acuminate. 



The antennular peduncles are not quite as long as the carapace. The 

 peduncles of the antennae reach to about the middle of the 2nd joint of
