the palm : the dactylus is as long as the palm, and the palm (which, like the 

 fingers, is curved) is broader than long. The edges of the merus are serrate, 

 especially the cristiform inner edge ; and the outer surface and edges — 

 particularly the lower edge and the prominent inner edge — of the wrist are 

 crisply granulous or spinulous. The lower edge of the palm and of the 

 broad short fixed-finger, and the upper edge of the dactylus, are thin, almost 

 cristiform, and very sharply serrated : the outer edge of the upper surface of 

 the palm is defined by a thin sharply-serrated crest, and the inner edge of 

 the same surface of the palm is much less distinctly defined by a row of less 

 regular and less distinct serrations. 



The slender left cheliped is setose and almost smooth, and hardly 

 reaches to the base of the right dactylus. 



The and and 3rd legs of both sides reach well beyond the large cheliped, 

 those of the right side being the longer : their joints are smooth, but there 

 is a spinule at the far end of the anterior border of the carpus : sometimes 

 the anterior border of the merus, carpus and propodite is distantly and very 

 faintly serrulate : the dactyli are plumose distally, those of the 2nd pair 

 being as long as their combined carpus and propodite, and those of the 3rd 

 pair being longer.
