(sometimes broken) row of granules, and between the same spine and the outer 

 angle of the buccal cavern is a row of granular tubercles : the surface of the 

 subhepatic region between these two rows of granules may, when denuded, be 

 granular or not. 



The chelipeds of the adult male are, especially in the male, much more 

 massive, compared with the legs, than is usual among the DrQuiiidse: they are 

 also much longer than any of the legs. The outer (exposed) surfaces of all the 

 joints are more or less granular, some of the granules on the palm being very 

 large and visible without denudation : in addition, the upper border of the arm 

 is denticulate, there are 2 coarse tubercles at the far end of the outer surface of 

 the wrist, and 2 on the palm just behind the finger-joint. 



The first 3 pair of ambulatory legs are short, and some of their joints are 

 granular and have a tendency to be nodulai', a nodule on the carpus being very 

 constant. Of these legs the 3rd pair ends in a characteristic stout talon-like 

 dactylus the tip of which bends towards a stout lobe at the proximal end of the 

 posterior border of the propodite. 



The 4th (last) pair of legs are very slender : they reach to the far end of 

 the carpus of the 3rd pair, and end in a tiny claw-like dactylus. 



In both sexes the abdomen has a convexity along the middle line. 



This species protects itself with the valve of a Lamellibrancli shell, which is 

 held, as in a frame, by the strong hook-like dactyli of the third jiair of legs.
