This species is very like D. diogenes, from which it differs in ihe following 

 particulars ; — 



The eyestalks are shorter and much thicker : they are less than two- 

 thirds the length of the anterior border of the carapace, and fall very far 

 short of the middle of the terminal joint of the antennal peduncle : the 

 eyes are much larger. 



The outer fork of the antennal acicle reaches ne^arly to the middle of, 

 and the inner fork well overlaps the base of, the terminal joint of the 

 peduncle : the antennal flagellum is shorter than the carapace, and is more 

 setose. 



Though the ed^es of their joints are spinose, the outer surface of the 

 chelipeds and legs is closely beset with sharp conical tubercles rather than 

 spines, and every tubercle is ornamented with a wreath of short stiff radiat- 

 ing setx'. 



The lefc cheliped is only half again as long as the carapace ; its merus 

 is as broad as long, its palm much broader than long, and its fingers shorter 

 and more compressed : the setose tubercles cover the whole of the outer
