The ambulatories aye very stout, stronger than the chelipeds, the 

 meral joints elongated, cylindrical, produced on each side at the distal 

 margin into a node, the carpus is two-thirds as long and similar to 

 the merus ; the propodus is four-fifths as long as the merus and almost 

 as stocky ; the dactyl is almost as long as the propodus, stocky, curved, 

 with a very strong, acuminate, brown tip. The first ambulatories are 

 practically as long as the chelipeds; the remaining pairs successively 

 decrease in size posteriorly; all are densely coated with stiff, brown 

 setae. 



The female abdomen is moderately ovate; vaulted in the median 

 line. The male belt is seven-segmented with its tip rounded.
