CALIFORNIA STALK-EYED CRUSTACEA. 149 



stout, a little longer than wide, the upper surface strongly convex and 

 thickly covered with small, sharp tubercles; inner edge spinous; hand 

 very wide and strongly flattened, with the edges produced into prominent, 

 thin expansions, which make the hand much wider than the carpus; both 

 surfaces thickly covered with small tubercles; inner edge of the hand 

 convex, denticulated, and curved downward in the middle; fingers strongly 

 compressed and hollowed out above, both sides minutely tuberculated or 

 granulated. Left cheliped with the merus flattened, denticulated on the 

 upper margin and at the infero-distal angle; carpus compressed, upper 

 surface granulated or tuberculated, the inner edge acute and spinous; 

 hand flattened, similar in shape to that of munitus, but the raised margins 

 are denticulated; upper surface granulated or minutely tuberculated, the 

 proximal margin overlapped by, instead of overlapping, the distal margin 

 of the carpus; lower surface smooth; fingers more or less pubescent. 

 Ambulatory legs nearly naked, and marked with red spots; upper margins 

 spinulous; dactyls slightly twisted, considerably longer than the propodi, 

 the margins and anterior surface spinulous; sides of the preceding joints 

 smooth and glossy. 



Length of large cheliped, 81 mm.; merus, 19 mm.; width of same, 16 

 mm.; carpus, 26 mm.;' width of same, 24.5 mm.; hand, 34 mm., greatest 

 width of same, 29 mm.; length of smaller cheliped, 51 mm.

Median tooth of the front low and scarcely in advance of the broadly 

 triangular lateral teeth. Ocular peduncles moderately stout and about 

 three-fourths as long as the anterior portion of the carapace, which is 

 nearly as wide as long. Eye-scales oblong, subacute, deeply channeled 

 above, and curved downward, the subterminal spine small. Acicle rounded, 

 pubescent on the inner margin, and not reaching the tips of the ocular 

 peduncles. Chelipeds of exceptionally unequal size; larger cheliped 

 glossy; merus trigonous, the surfaces convex and nearly smooth, but 

 slightly roughened with scattered, minute prominences; carpus much 

 widened at its distal end where its breadth about equals its length; upper 

 surface convex and furnished with scattered, depressed granulations; outer 

 margin raised and finely granulated; inner margin prominent and armed 

 with several short, unequal spines; outer surface more or less flattened; 

 inner surface oblique and slightly concave; hand flattened, much wider
