on its distal border ; the carpus is about as long as the palm and granu- 

 lose with two longitudinal ridges of denticles on the upper surface ; the 

 area between these ridges is usually, but in old specimens not always, 

 sunken ; the propodus is twice as long as wide and also has two longi- 

 tudinal ridges, composed of denticles on its upper surface and in line 

 with those of the carpus ; these regions have a depression between them 

 and terminate at the base of the fingers ; the remaining surface of the 

 propodus is granulose, and the outer lateral margin is denticulate; 

 the fingers are long, slender, not gaping. 



The first and second ambulatories are quite long and slender, ex- 

 ceeding the great cheliped by two-thirds the length of the dactyl ; the 

 dactyli are very acuminate, each being one and one-half times as long 

 as its related propodus; there is a deep longitudinal groove on each 

 face of the dactyl, extending from its base almost to the tip. The 

 meral joint is spinulose on its upper distal surface. 



The fourth and fifth legs offer no specific characters. 



The eyestalks are stocky, constricted at the base of the cornea, which 

 is substantially larger than the stalk. The ocular scales are short, sub- 

 triangular, wide at the base, with an obscure subterminal spine. 



The acicules are not quite as long as the eyes.
