liquely on the outer surface of the tip of the stalk. The male belt is 

 six-segmented, the third and fourth articles being fused. The female 

 belt is widely oval, and seven-segmented. 



The chelipeds are equal, but those of the male are substantially 

 more massive than those of the female. Each has the merus triquetral, 

 with the upper margin strongly crested, the crest distally expanded 

 foliaceously and deeply cleft, the upper lateral margin shaggily 

 setose; the carpus is smooth, convex dorsally, with a strong double 

 tooth at the upper and inner angle ; the propodus is smooth, rounded, 

 with a longitudinal shallow groove, terminating distally near the base 

 of the upper finger. The fingers meet throughout their length and are 

 long, slender, down-curved, with the cutting edges shallowly serrate. 

 Both fingers are black ; the color terminating at the base of the fingers 

 on the female, but on the males, (at least on the large males) extend- 

 ing on the palm three-fourths of its length along the base and upward 

 on both inner and outer surfaces for a less distance, but quite promi- 

 nently terminating in a conspicuous blotch on each surface behind the 

 base of the lower finger. 



The ambulatories are smooth, with the merus, carpus and propodus 

 decidely crested on the upper surface, the inner surface of this crest 

 covered with shaggy setae ; dactyl coarsely villous up to the tip, which 

 is a curved, highly polished claw.
