the peduncle, and having the outer margin armed with short spines; sec- 

 ond joint of the peduncle produced, external to the acicle, into a process 

 which is cut into three spines. Legs pubescent. Chelipeds equal, the 

 merus nearly smooth; carpus with a flattened, subtriangular upper surface, 

 the inner and outer margins of which are armed with three or four short, 

 stout spines; hands with the upper surface coarsely granulated; the short 

 inner margin armed with three short, stout spines; a longitudinal intu- 

 mescence on the upper surface upon which are two rows of small tubercles; 

 fingers excavated within and having black, corneous tips. The upper 

 margins of the carpi and propodi of the ambulatory legs are spmulous; 

 dactyls scabrous, slender, nearly straight, and longer than the propodi. 

 Length one-half inch.

Carapace hairy, the anterior portion nearly as wide as long, eroded in 

 front and towards the sides, and having a few short spinules near the 

 antero-lateral margins; front with three, subequal, triangular teeth. Ocu- 

 lar peduncles slender, cylindrical, two-thirds the length of the anterior 

 portion of the carapace, and having a line of hairs on the upper side. 

 Ocular scales armed with several marginal spines which become larger 

 towards the tip. Peduncle of the antennae nearly three-fourths the length 

 of the eye-stalk; second basal joint with a spine at the autero-internal 

 angle; the antero-external angle produced forward as a large, triangular, 

 acute process which is armed with a few short spines on the outer margin. 

 Acicle rather small, awl-shaped, hairy, reaching a little beyond the middle 

 of the last joint of the peduncle, the inner margin armed with spines and 

 the outer margin furnished near the tip with two spinas which point 

 obliquely upwards. Chelipeds equal; merus trigonous, the upper ante- 

 rior end hirsute and spiny and the two lower margins armed with short 

 spines; carpus short, hirsute and spiny above, the inner margin of the 

 upper side armed with about six spines which increase in size anteriorly; 

 outer face small, hard portion of the lower side reduced to a narrow, trans- 

 verse bar, inner face flattened, with a concavity on its lower side, and 

 armed with a few spines above and auteriorlj'^; hands short and broad, 

 widest across the base of the pollex, the upper surface flattened, hairy, 

 armed with numerous spines, inner edge straight, the outer very strouglj'^ 

 curved, inner faces flattened and armed with small spines, four spines on 

 the inner margin behind the base of the dactyl; pollex very broad at base;
