CALIFORNIA STALK-EYED CRUSTACEA. 141 



slender and exceeding the tips of the ocular peduncles. Chelipeds spinu- 

 lous and pubescent; merus oblong, the supero-lateral surf ace rounded and 

 scabrous, or spinulous; lower surface spinulous, and devoid of marked 

 prominences; carpus thick, oblong, the inner and outer surfaces flat; 

 upper surface convex, spinous, with the inner and outer edges defined by 

 rows of spines; hand about as wide as the carpus and over twice as long 

 as broad; on the upper surface behind the gap between the fingers is a 

 longitudinal ridge, which is continued forward upon the pollex though 

 diminishing in size; the ridge bifurcates behind, forming two lower, less 

 marked ridges which diverge toward the posterior margin; on either side 

 of this ridge the surface of the hand is depressed and less spiny than 

 elsewhere; fingers flattened and bent downwards; a row of short spinules 

 on the outer margin of the dactyl and a similar row near it on the upper 

 surface. Merus of the smaller cheliped compressed, spinulous below; 

 carpus compressed, but widened at the distal end of the lower side, having 

 a rounded, spinulous process at the antero-external angle; upper edge 

 with two series of spines; hand trigonous, supero-external face subtrian- 

 gular, deeply concave; edges prominent, spinulous; a row of spinules 

 extending from the proximal margin to the upper ridge, which it meets a 

 short distance from the base; the surface below the upper edge is concave 

 and limited below by a row of spinules; fingers curved downwards; dactyl 

 slender, nearly smooth. Ambulatory legs subequal, spinulous above; 

 dactyls slender, longer than the propodi, quite strongly twisted, and 

 obsoletely spinulous.

Very near Tanneri. The median lobe of the front is acute but not so 

 prominent as in that species. Ocular peduncles short, stout, distally 

 widened, and not two-thirds the length of the anterior portion of the 

 carapace. Chelipeds much like those of Tanneri; the larger hand is 

 slightly wider, with the outer margin more curved; the triangular area 

 between the two diverging ridges of the upper surface is wider, and the 

 more prominent inner ridge is interrupted at about its posterior third, the 

 two parts changing direction at this point; the elevated apex of the tri- 

 angle where the ridges meet is not continued forward as a high crest as in 

 Tanneri, but the ridge begins to descend immediately toward the pollex; 

 fingers much flattened, but scarcely curved downward. Smaller hand 

 scarcely distinguishable from that of Tanneri. Ambulatory legs subequal; 

 dactyls slender, curved, twisted, nearly devoid of spinules.
