minute spinulose denticulations, which are continued along the 

 outer angle and lower edge of the orbit; this lower edge is incom- 

 plete, and terminates at the base of the outer antennae in a spine, 

 adjacent to which is another somewhat smaller, forming the ante- 

 rior termination of the outer border of the buccal frame. Basal 

 segment of the exterior antennas somewhat flattened, outer edge 

 • terminating anteriorly in an acute prolongation at the articulation 

 with the second segment. 



First pair of feet, of moderate length, third segment stout, with 

 numerous piliferous denticulate ridges ; carpus compressed, surface 

 with granulations and denticulate ridges, upper border termina- 

 ting with an acute spine above the articulation with the hand ; the 

 line of this articulation appears to lie in the prolongation of the 

 lower border of the carpus even more decidedly than in Ranina 

 dent at a ; hand much compressed, almost flat, lower edge sub- 

 trenchant, nearly straight, ornamented with a raised border with- 

 out denticulation, even the slightest, and terminating in a stout, 

 moderately curved tooth, which is opposed to the tip of the termi- 

 nal segment, or moveable finger; upper edge of the hand much 

 arched, granulate, and furnished with a spine a little in advance 

 of its middle; both surfaces of the hand are, like the carapax, 

 polished, and covered with piliferous denticulate ridges. The last 

 segment or moveable finger polished, moderately curved, outer edge 

 with a double line of granules near the articulation, trenchant 

 edge without vestige of teeth, the opposing edge of the hand is 

 furnished about the middle with a single large lamellar tooth. 



Feet of four last pair resemble very much those of Ranina den- 

 tata, but, in general, the segments are less cylindrical, in some 

 pairs quite flat. The forms of the tarsi are nearly the same as 

 in Ranina, those of the third pair are not flat, but rather triangu- 

 larly prismatic, with the under or anterior surface nearly plane, 

 and the outer edge of the prism forming a prolongation beyond 

 the articulation with the fifth segment, for nearly one-third the 

 length of that segment; the tarsi of the fifth pair are not more 

 than half the breadth of the tarsi of the fourth pair; the fourth 

 segment of the fourth pair has a tooth-like prolongation of the 

 posterior edge, which reaches beyond the middle of the fifth seg- 

 ment; the anterior and posterior edges of most of the segments 

 of the four last pair of feet are fringed with long hairs, the hairs of 

 the piliferous ridges of the sternal plate, pterygostomian regions
