CANCROIDEA. ^99 



the sulci very narrow, minutely tomentose, areolets flat, 2 M partly 

 subdivided, 3 M tripartite, anterolateral margin four-lobed, postero- 

 lateral concave and short. Feet all granulous and nearly naked, 

 margins not ciliate, hand and carpus with the surface irregularly 

 areolate, outer surface of hand with the granules seriate, fingers 

 very short, imperfectly excavate, moveable finger when shut having 

 nearly a vertical position ; fourth joint of second, third, and fourth 

 feet with the surface tripartite.

 male abdomen.

Length of carapax of male, 3*66 lines ; greatest breadth, 5 lines ; 

 ratio of length to breadth, 1 : 1-37. The carapax has a bare look, as 

 the pubescence between the sulci and between the granules is very 

 short, even shorter than the granules, and the granules of the areolets 

 are very crowded. The surface of the areolets is flat, and the sulci 

 very narrow. Areolet 2 M is divided about half way through. The 

 upper surface of the hand is a little broad, and is divided obliquely 

 by a depression, and a parallel depression extends from the hinder 

 margin of the same surface. The outer surface of the carpus is 

 divided into three parts by vertical depressions, and there is an imper- 

 fect longitudinal depression above. The moveable finger has some 

 granules on its upper side, so also the under surface of the hand; and 

 similar granules cover the under side of the third joint of the four 

 posterior legs. The outer maxillipeds are naked on the outer surface 

 or nearly so ; the sternum is in part slightly villous. The tarsus is 

 very short and stout, and granulous, with a slender claw.
