" The two species," says Benedict, " are readily separated by the inner 

 side of the raised triangle of the larger hand. In this species it cuts off 

 the inner depression of the upper surface from the proximal margin of the 

 pnlm, while in Tanneri this depression is allowed to reach the margin by 

 a curvature of the ridge."

Anterior portion of the carapace longer than wide. Median frontal tooth 

 short and obtuse; the lateral teeth broadly rounded and slightly promi- 

 nent. Eye-stalks moderately slender and a little over one-half the length 

 of the anterior portion of the carapace. Eye-scales subtriangular, slightly 

 concave above, the subterminal spines prominent. Antennal peduncles 

 longer than the eye-stalks; acicle nearly reaching the tip of the eye. 

 Chelipeds very unequal; merus of the larger one stout; the outer surface 

 is convex and nearly smooth, but there are some transverse spinulous 

 rugae near the supero-distal angle; two prominent tubercles on the lower 

 side; carpus oblong, scarcely one-half longer than wide, and of nearly 

 equal width throughout; outer surface flat; inner surface a little concave; 

 upper surface evenly convex, thickly covered with spiny granules, and 

 bordered on the inner side by a row of short spines, internal to which is 

 a parallel row of smaller spines; hand no wider and scarcely longer than 

 the carpus, and covered above with spiny granules; outer edge acute, 

 especially on thepollex, and armed with short spines; fingers with minute, 

 corneous tips; dactyl margined with spiny granules. Small cheliped 

 pubescent; merus compressed, and more or less spinulous below; carpus 

 armed with ten or twelve long, curved spines on the upper edge; outer 

 surface with several spines on the i;pper side and spiny granules further 

 down; hand longer than the carpus, with a triangular, spinulous, supero- 

 external face; a sulcus on the posterior portion of the upper edge. The 

 carpus and propodus of the ambulatory legs are armed above with spines, 

 which are much smaller in the second pair, where they may be absent on 

 the propodi; dactyls spinous below and about as long as the propodi. 



Color in alcohol: chelipeds reddish, the tips of the fingers bright red. 

 The ambulatory legs are spotted with red; the base of the dactyls and the 

 distal end of the propodi are bright red.
