than the carpus, and nearly as broad as long; upper surface evenly convex 

 and covered with sharp granulations of unequal size; outer margin acute, 

 denticulated, and evenly curved from the tip of the pollex to the base; 

 inner margin produced, acute, more strongly denticulated than the outer, 

 and ending in a prominent angle some distance from the base of the 

 dactyl; fingers compressed; pollex very wide and furnished with several 

 large granulations; dactyl with the upper margin sharply granulated and 

 furnished with a granular line on the surface, between which and the outer 

 margin the surface is deeply concave. Merus of the smaller cheliped 

 compressed, narrow, and smooth, except on the lower side, which is spinu- 

 lous toward the distal end; carpus compressed, armed above with two rows 

 of spines, the included surface being slightly concave; hand small, oblong, 

 with no prominent angles, a little longer than the carpus, but not exceed- 

 ing the merus. Ambulatory legs glossy, nearly smooth; a spine at the 

 supero-distal angle of the carpus projecting over the propodus; dactyls 

 thin, pubescent, not twisted, and spinulous below, exceeding the length 

 of the propodi. 



Color of alcoholic specimens near orange; the ambulatory legs crossed 

 by bands of a lighter color. There is a band of lighter color near the 

 middle of the ocular peduncles.

Carapace smooth, nearly naked, the anterior margin with three nearly 

 equal teeth. Eye-scales oblong, channeled above. First joint of the 

 antennal peduncle with a spine or tooth at the interior antero-inferior 

 angle; second joint with a spine at the antero-internal angle, the infero- 

 distal produced forward into a prominent spine which is generally double 

 pointed; third joint with a spine at the apex; acicle rounded, pubescent 

 on the inner side, and about reaching the tips of the ocular peduncles. 

 Chelipeds very unequal, merus of the right cheliped short, trigonous; car- 

 pus broader than long, the margins produced into two large, thin, wing- 

 like expansions and curved so that the inner surface is concave; hand 

 smooth, much narrower than the distal end of the carpus, and about 

 twice as long as wide, the edges subparallel; outer edge slightly concave; 

 fingers punctate, shorter than the palm. In the smaller cheiiped the car- 

 pus is elongated and compressed, the upper margin spiny; hand oblong, 

 smooth, much flattened, the acute edges upturned, making the upper sur- 

 face markedly concave; proximal margin acute and overlapping the distal
