2l8 SMITHSONIAN MISCELLANEOUS COLLECTIONS 



left hand; from B. hcrnhardns in the shorter e_\es, the nKjre elon- 

 g-ated and slender feet, and the smoother, flattened hand with lamelli- 

 form outer edge. 



It was dredged off the east coast of Niphon, in north latitude 

 about 38°, at the depth of thirty fathoms. Found also in Hakodadi 

 Bay.

The acicle of the outer antennze in this species is remarkable for 

 its trigonal form and its naked, glossy, iridescent surfaces. The 

 dactyli of the ambulatory feet are long, naked, and as much twisted 

 as in B. bernhardus. 



We found two adult specimens in Hakodadi Bay, the largest over 

 four inches in length. The original specimen of Dana's B. armatus 

 differs from ours in one point only — the greater hand is more elon- 

 gated and more rounded at its extremity. This, however, is prob- 

 ably nothing more than a mark of immaturity or variety, as other 

 species are often variable in the proportions of the carpus and hand, 

 so that this may be regarded as one of the species common to both 

 sides of the North Pacific Ocean.

Body broad and thick ; abdomen rather small ; sternum somewhat 

 narrower than in B. bernhardus. Anterior part of the carapax con- 

 vex, much indurated, with two arcuated, converging rows of fas- 

 cicles of setse, almost obliterated in old specimens. Rostriform point 

 prominent and rather sharp; angle about 60°. Lateral teeth (be- 

 tween eyes and antennae) acuminated, less prominent than the ros-
