Chelipeds in the female not half as long again as the carapace : 

 the outer surface of the arm and wrist are rugulose, and both surfaces of 

 the palm are studded with sharpish granules : the upper border of the 

 arm ends acutely, but there is no spine at the end of the inner border; 

 the inner angle of the wrist is pronounced, almost dentiform ; there are 

 no granular or pectinated crests of any kind on the palm : the fingers 

 are little bent and leave no large gap between them when closed, there 

 are some sharpish granules along the upper border of the dactylus, and 

 along the lower border of the fixed finger. 



The legs are remarkably uneven in length, the third pair being 

 more than 2| times the length of the carapace ; the meropodites are 

 not exactly foliaceous, their greatest breadth being hardly two-fifths of 

 their length, and they have a subterminal spine on the anterior border 

 only ; the dactyli are remarkably long, those of the third pair being as 

 long as their propodites. 



In the Indian Museum are 2 females from the Andamans : the 

 carapace of the larger one is 18 millim. long and 20 millim. in its 

 greatest breadth posteriorly.

Differs from 8. longipes, which it closely resembles, in the following 

 characters : — 



(1) the four post-frontal lobes are not so prominent, the outer ones, 

 indeed, being very inconspicuous : 



(2) the free edge of the front is more sinuous, owing to the depth 

 of the median notch : 



(3) there are two distinct teeth on the lateral border of the 

 carapace, behind the outer orbital angle : 



(4) the outer surface of the wrist and both surfaces of the palm 

 are nearly smooth, and there is a row of sharp granules along the 

 outer surface of the fixed finger: the upper border of the arm does nob 

 end acutely : 



(5) the legs are even longer and slenderer, the 3rd pair being more 

 than 3J times the length of the carapace : the meropodites of the legs 

 are at least 3 times as long as broad. 



In the Indian Museum is a single male from the Nicobars : its 

 carapace is 9 millim. long and 11 millim. in greatest breadth.
