Differs from G. Grayi in the following particulars : — 



The carapace is quite flat, and the lateral borders, which are thin 

 and well defined throughout their extent, are slightly divergent poste- 

 riorly : the transverse markings are distinct and nearly straight. 



The four tubercles along the line of flexion of the front are salient, 

 and the free edge of the front is quite straight. The notch near the 

 outer end of the lower border of the orbit is large, and the lobule 

 external to the notch is denticulate. The epistome is well defined 

 from the palate by a granular or pectinate ridge. 



The chelipeds in the male are nearly equal, but in the female they 

 are unequal. The squamiform markings on the arm, wrist, and lower 

 portion of the hand are distinct, as also are the vesiculous granules on 

 the upper surface of the palm and dactylas. 



The greatest breadth — near the far end — of the meropodites of the 

 last 3 pairs of legs is more than half their length. 



Colour in life bright red. 



In the Indian Museum are 2 males and a female from the Anda- 

 mans, a male from the Nicobars, and a female from the Laccadives. 

 The carapace of a female is 40 millim. long and 45 broad.
