second article with a row of unequal spines on 

 anterior border ; third article short, smooth. 



Chelipeds subequal, stout; merus crossed by a 

 rew rugae distally, a rugose and serrate spine at 

 inner distal angle; carpus with four anterior 

 spines, graded in size, proximal one largest, and 

 upper surface with four prominent longitudinal, 

 tuberculate ridges, with deep channels between, 

 channels crossed by irregular septae forming rows 

 of oblong pits between ridges; ridges and pitted 

 channels continued on hand but with less regu- 

 larity in arrangement; fingers tuberculate almost 

 to tips. First three pairs of walking legs stout and 

 with distal articles hairy ; last legs weak and re- 

 flexed dorsally. 



Telson of male and female with five elements; 

 male pleopods present.

 nute, irregular, transverse rugae; anterolateral 

 margins with two more or less obtuse spines on 

 each side behind antennae. Front tridentate, 

 median spine about twice length of lateral spines, 

 a broad V-shaped depression at rear edge of cara- 

 pace. Eyes well developed. Antennule short. 

 Antenna about three- fourths length of body, fla- 

 gella sparsely covered with fine hairs; basal
