Description of female.—Of small size. Carapace thin, but fairly firm, of equal length and width, very convex, subhexagonal, the side-margins parallel behind antero-lateral angles, the postlateral portion of the branchial region forming a steep facet strongly in- clined to remainder of dorsal surface; cardiac region surmounted by two small tubercles side by side; cardiac and posterior gastric region defined by shallow grooves; posterior margin convex. In ventral view the posterior line of the antennular cavi- ties, of the minute, basal segment of the antennae and the lower border of the orbit form a single transverse line. Buccal cavity broadly hemispheri- cal ; penult segment of outer maxilliped broadly obliquely-truncate: last seg- fiq. 49. — pinnotheues taylobi. ment small, attached near distal end of endognath of outer maxilliped ,.'

Chelipeds hairy inside; manus much inflated, upper and lower margins convex; fingers equally stout, tips strongly hooked, a small tooth near base of dactyl, a larger tooth or lobe near middle of im- movable finger. The chelipeds are shaped much as in pugettensis hut are much smaller, specimens of subequal size compared. Of the ambulatory legs, 1 and 4 are subequal, shorter than 2 and 3, which are subequal; propodi convex on anterior and straight on posterior margin; dactyli shorter than propodi, curved and with slender tips, that of first leg shorter then the o
