Carapax quite broad, below villous throughout, above granulous, 

 nearly naked, throughout areolate, sulci naked or hardly tomen- 

 tose, areolets minutely granulous, very convex, and a little irre- 

 gular, 2 M subdivided, 3 M tripartite, anterolateral margin irregu- 

 larlv five-toothed. Feet granulous; anterior subcqual, hand and 

 carpus in part granulous, and with deep cavernous excavations, 

 hand seriato-«ranulous on outer surface, fiuely tomentose, fingers 

 imperfectly excavate, scabrous, striate, in part minute tomentose; 

 posterior legs a little hirsute, third and fourth joints above strongly 

 cristate, crest entire, lunulate, sublateral, this crest and the upper 

 margin of the feet including a large cavity.

Length of carapax of a female, five lines ; greatest breadth, seven 

 and three-fourths lines; ratio of length to breadth, 1 :1'55; a smaller 

 female, length, three and three-fourths lines; breadth, five and three- 

 fourths lines; ratio, 1 : 1*53. In the larger specimen, the sulci are 

 rather broad and naked or nearly so, and the areolets arc very promi- 

 nent and gibbous. In the smaller, the sulci are quite narrow, the 

 granules extending nearly to meeting from the opposite sides. In 

 neither are there any hairs on the carapax longer than the granules, 

 and but slight traces of any viliosity can be detected. The cristate 

 posterior legs give a peculiar look to the species, the crest being 

 curved and sublateral, and enclosing between it and the upper margin 

 of the leg, an oblong cavity. The anterior legs have pits or cavities 

 excavated in the upper part of the hand, and in the outer surface of 

 the carpus. In the smaller specimens the eight posterior legs are not 

 as hirsute as in the larger one, being but slightly so. The outer 

 maxillipeds, pterygostomian region, sternum and abdomen are all 

 short hirsute. The fingers are not very perfectly spoon-shaped. The
