Differs from G. Marionis only in the form of the large hand of the 

 adult male : this member, iu var. nitidus, 



(1) is not much over 2| timed the length of the carapace, its 

 dactylus being but little more than twice the length of the upper border 

 of the palm : 



(2) it has the two obliqae granular ridges on the inner surface of 

 the palm remarkably salient : 



(3) it has the dentary edge of the immobile finger thrown into a 

 characteristic W-shaped curve owing to the strong projection of two 

 large triangular lobes, and 



(4) ib has the dactylus somewhat hooked at tip. 



In the Indian Museum are 103 specimens, chiefly from the Anda- 

 mans and Nicobars, but also from the Coromandel and Malabar coasts. 

 The length of the carapace in large specimens is 14 millim., the breadth 

 21 millim.
