Antero-lateral border cut into four thin shallow teeth, of which 

 the first two are rounded and the last two are anteriorly acuminate, 

 the first being the least prominent of all and the last being the smallest 

 of all. The antero-lateral border is extremely short, a good deal less 

 than two-thirds the length of the postero-lateral. 



Supra-orbital margin entire, the infra-orbital finely denticulate. 



Chelipeds markedly unequal, perfectly smooth, inner angle of 

 wrist rather strongly pronounced ; the hand and fingers are rather short 

 and stout and the thnmb of the larger cheliped is a good deal shorter 

 than the hand and has a very strong tooth at its base. 



The legs and under surface of the body are covered with a dense, 

 extremely short scurfy tomentum. 



Colours in spirit yellowish brown. 



In the Indian Museum are four specimens, from Karachi, Bombay 

 and the Andamans. 



This species agrees in all respects with the descriptions and figures 

 of Eurycarcinus maculatus, except in respect of the antero-lateral 

 borders. These are so short that a line joining their posterior ex- 

 tremities would divide the carapace into two halves, of which the 

 anterior would be much the smaller : the teeth of the antero-lateral 

 border are also much shallower and less salient.

Carapace about two- thirds as long as broad, strongly convex fore 

 and aft, slightly so from side to side, perfectly smooth to the naked eye. 



Front cut square, emarginate in the middle line, the fore edge 

 straight but sloping a little obliquely from the outer angles to the 

 middle line. Supra-orbital margin entire, the infra-orbital obscurely 

 denticulate. 



Antero-lateral border as in E. orientalis but rather longer, its 

 length being at least two-thirds that of the postero-lateral ; the edges 

 of all the teeth are a little thickened and granular. 



Chelipeds unequal, perfectly smooth, inner angle of wrist pro- 

 nounced : the hand is more elongate and narrower and the fingers are 

 slenderer than in E. orientalis, and the thumb of the larger cheliped has 

 no enlarged tooth at the base. The legs, the smaller cheliped, and the 

 under surface of the body are covered with a dense, extremely short 

 and fine tomentum. 



Colours in spirit, yellowish brown. 



In the Indian Museum is a single specimen from the Nicobars.
