the larger cheliped is wider than its superior length, and the upper 

 margin is somewhat flattened. Tlie inferior margin of the propodus is 

 slightly sinuous. The surface is punctate with large and small punctte, 

 and finely granulate, the granules becoming larger and rougher on the 

 broad upper surface. The fingers are wide and gape slightly. They 

 are crossed by a few impressed, punctate lines. The dactylus is arched 

 and has a large basal tooth, followed by about seven small teeth. The 

 pollex has about six large teeth. The lesser cheliped is missing in the 

 type male. In a smaller specimen, however, this cheliped is seen to 

 differ from the larger one in being a little narrower, with fingers bent 

 down a little more. All the prehensile teeth are small. The meral 

 joints of the ambulatory legs are narrow, with anterior margins spinu- 

 lous. The next joint is subcristate, having a deep groove near its ante- 

 rior margin; the i)ropodi have convex margins.'
