The chelipeds are markedly unequal, the larger one being less than 

 twice the length of the carapace. The anterior and posterior edges of 

 the arm are granular ; the wrist has the upper and outer surfaces 

 studded with granules and conical spine-like tubercles ; similar tuber- 

 cles and pearly granules stud the upper and more or less of the outer 

 surface of the hand ; the finger has a few spinule-like tubercles at base. 



The legs have the upper border of the meropodite, carpus, and 

 propodite denticulate. 



Colours in spirit ; brownish yellow or mottled green, the mottling 

 on the legs forming indistinct cross-bands ; fingers black, the coloura- 

 tion involving the greater part of the lower border and both surfaces of 

 the lower outer corner of the hand. 



In the Indian Museum are 35 specimens from the Andamans. 



This species is at once distinguished from G. pilumnoides, (1) by 

 the smaller size, (2) by the better defined areolation of the carapace, (3) 

 by the cap of spinelets — instead of a large claw-like spine — on each of 

 the 4 lobes of the antero-lateral margin, (4) by the marked inequality 

 of the chelipeds, and (5) by the black colouration of the thumb extending 

 far back along the hand.

Carapace and chelipeds with a few scattered hairs, legs with 

 numerous long stiff brown and yellow hairs that a good deal conceal 

 the sculpture. 



The regions and subregions of the carapace in its anterior f are 

 most remarkably well defined by broad smooth deep-cut grooves, and 

 are coarsely and unevenly granular. 



The front is cut into two lobes which have their free edge entire or 

 slightly crenulate, and their outer angle isolated and spine-like. The 

 orbital margin is sharp-cut and almost smooth : the 3 fissures are distinct. 



The antero-lateral margin is cut into four teeth, of which the first 

 is always small and often obsolescent, while the other three are large, 

 procurved and claw-like. The three or four lobules of the carapace 

 just inside and parallel with the antero-lateral border have the form of 

 salient conical tubercles.
