Carapax polished, swollen, nearly quadrate. Meros of the 

 larger cheliped with the outer surface rugose, upper and lower 

 margins crenulate. Carpus granulate externally, its inner margin 

 acute; hand inflated, the basal portion granulate and margined 

 above and below ; inner surface rounded, granulate, but without 

 any trace of a tuberculate ridge except one formed by a continua- 

 tion of the inner margin of the thumb. Thumb nearly straight, 

 a ridge on the outer surface, a large tubercle near the middle of 

 the inner margin, the extremity obliquely truncate. The finger is 

 longer than the thumb, i-egularly tapering and distally strongly 

 arcuate. There is a specimen in the collection of the Philadelphia 

 Academy from Surinam which appears to be intermediate, in the 

 characters of the hand, between this and G. vocator. The fingers 

 are shorter, the granules on the outside of the palm much more 

 prominent than, in typical pugillator, and there are traces, though 

 faintly indicated of a tubercular ridge on the inside of the 

 palm.
