finger a sharp tooth at the middle, and a molar process at the base 

 which is divided into two or three teeth; the smaller chela has the 

 lower margin coarsely granulous and hairy, fingers less deflexed, 

 almost meeting, teeth of propodus larger than those of dactylus, 

 with three of them enlarged. 



First three legs similar, fourth much shorter, with upcurved dactyl. 



First segment of abdomen linear; second short, with pointed ends; 

 third with outer angles rounded, surface convex except at the middle; 

 remainder of abdomen suboblong. 



The narrow front, round orbits and large chela with its few prehen- 

 sile teeth easily distinguish this species.
