cheliped, and in the shape of the hand, which is, however, usually 

 tapering toward the fingers, so that the immovable finger is narrow, 

 with a nearly straight outer margin. 



The rostriform point is smaller and less prominent than in Dana's 

 figure, but sharp and distinct. The right cheliped is elongated, does 

 not reach to the extremities of the right ambulatory feet ; the gran- 

 ules of its upper surface are distinct and well separated, though not 

 generally very prominent ; those of the carpus are sharper or scabri- 

 form, and always setose at their bases ; the dactylus is ornamented 

 with a row of granules parallel to its outer margin, not represented 

 in Dana's figure. The small cheliped is convex and distinctly 

 grooved longitudinall}^ above, particularly on the carpus, where the 

 groove is defined on either side by a spinous crest, the superior crest 

 being by far the most prominent. Fingers of the smaller hand not 

 gaping, and not over a third or half longer than the palm. Beneath 

 the meros-joint is hairy in both chelipeds. In the small cheliped the 

 sides of this joint are prominent and denticulated with subequal 

 teeth; the surface is granulated. In the larger cheliped this joint is 

 sparsely granulated, one granule or tubercle situated near the apex 

 of the ischium being larger than the rest, but not projecting. 



Neither the shape of the anterior part of the carapax nor the gran- 

 ulation of the chelipeds is well represented in the figure taken from 

 the U. S. Exploring Expedition specimen. 



It differs from B. pubcscens in the armature of the hands, which 

 are not spinous, but granulated, and in the shorter dactyli of the 

 ambulatory feet, which are very little longer than the penult joint, 

 and show a longitudinal red stripe on each side. 



It is found at Hakodadi, in Japan, in the same abundance as on 

 the opposite shore of the North Pacific.

Closely allied to B. hirsutiusculus. The rostriform point is slen- 

 der, sharp, and distinct in some specimens, but generally obtuse or 

 hidden by a tuft of setae. The feet are hairy, but much less so than 

 in hirsutiuscuhis; chelipeds usually naked. On the lower surface of 

 the meros-joint in the chelipeds there is a remarkably prominent 

 tubercle, sometimes sharp, but usually blunt, situated near the mid-
