Body and appendages tomentose. 



Carapace deep — nearly as deep as broad — convex, from a fourth to a fifth 

 longer than broad, its greatest breadth being just in front of its posterior border : 

 except for a few sharp granules antero-laterally and along the ill-defined lateral 

 borders it is smooth, and the regions are hardly indicated. The front is deeply 

 cleft to its base, into two acutely triangular teeth. 



Upper margin of orbit notched near its outer angle which is dentiform, the 

 outer angle of the lower margin of the orbit is much more strongly dentiform, 

 and the (outer) orbital wall between the two spines is deficient. 



Antennal flagella longer than the carapace. The antennal and antennulai- 

 peduncles both surpass the tip of the front by their terminal joint. 



Chelipeds rather slender, unarmed except for a few granules seen on denuda- 

 tion, about If times the length of the carapace: fingei's strongly hollowed 'en 

 cuiUrre^ especially the fixed one, which alone has teeth : wrist not elongate, 

 about as long as the dactylus and a little shorter than the palm. 



First two pairs of legs more than twice the length of the carapace : their 

 dactyli are about two-thirds the length of the preceding joint, are stout, are 

 sharply spinate along the posterior edge, and end in a claw. The last two pairs 

 of leo-s are about the same length as the carapace : their small claw-like dactyli 

 shut down on a ring of spines at the end of the preceding joint. 



Colours in spirit : dirty white, with a bluish tinge on the carapace and a faint 

 reddish tinge elsewhere ; eyes chocolate.
