Description. — A rough species. Carapace broad; regions plainly 

 marked, granulate except in the depressions, and covered with a short, 

 thin pUe. AH the spines, spiny tips and spinules, however small, 

 are conspicuously white in preserved specimens, in contrast with the 

 darker color of the body. Hepatic region spinulous. Antero-lateral 

 spines five, including a very small one at the orbit; second to fifth 

 spines set in stouter, denticulate bases; third and fourth largest, sub- 

 equal, curved, the second and fifth subequal, second curved, first and 

 fifth straight. Orbital margin spinulous; on the upper margin the 

 spinules diminish on the inner half to granules; they are somewhat 

 larger on the lower margin, interrupted on the outer half by a broad, 

 pointed sinus, and extending inward to a large, triangular, granu- 

 lated tooth. An oblique row of a few white spinules on the eyestalk 

 at inner base of eye. Frontal lobes slightly arcuate; edge finely 

 denticulate, separated by a very small median notch but not sharply 

 divided from the outer angle which is subrectangular, not advanced and 

 edged with two minute white granules. Endostomial ridge obscure. 



Chelipeds rough and bristling ; two long spines above merus ; carpus 

 heavUy spined, the longest spine at inner angle; one equally long 

 below it in minor cheliped; minor palm spinous on the entire outer 

 surface; on the major palm the spines change to coarse granules below 

 and distad. Fingers deeply grooved, especially the minor pair, where 

 the ridges are armed with sharp granules. Legs rough except on 

 those flat surfaces of the dilated merus which are subject to friction; 

 long-hairy on the lower surface, and also on the upper surface of the 

 last three articles; propodus dilated; dactylus long, slender, curved, 

 with a light brown, horny tip of needle-like sharpness. 



Third, fourth, and fifth segments of male abdomen fused.
