The outer maxillipeds are smaller and do not attain the epistome, 

 and their position is more longitudinal than in G. ruricola; the 

 ischium is considerably longer than the merus and the latter has a 

 shallow emargination on its anterior border. 



Chelipeds very unequal in old males, less so in young males, equal 

 or nearly so in females; the gape of the fingers being greater in the 

 large cheliped than in the small one. In old specimens the spines of 

 the carpus are obliterated. 



Dactyli of legs with only four rows of spines, the ridge on the 

 upper and the lower surface being unarmed, except that occasionally 

 there are a few spines near the tip, or less frequently a whole row 

 of very feeble spines.
