deeply flexuous behind, slightly thickened, and reflected; body with a wash 
of glossy white callus; pillar very short, obliquely truncate, moderately 
callous; canal wide, very short, sharply recurved, with a well-marked 
fasciole. Long, of shell, 60; of last whorl, 40; of aperture, 29; max.

Shell ovate, conical, rather ventricose, thin white; whorls ventricose, 
closely transversely plaited, and deeply and closely spirally striated, the 
upper one with a subposterior, and the last with three or more elevated 
keels. Mouth ovate, inner lip much absorbed; canal only slightly recurved. 
(Gray.) 
This shell is very like B. glaciate in form, but the whorls are deeply 
striated and closely plaited. The shells of this kind appear to be formed 
of two coats, an opaque dead-white external one, and a hard pellucid- 
white inner one; the outer one is often eroded, from the apex of the Polar 
species leaving the under one exposed, which being smooth, polished, and 
without striae give the tips of the shell quite a different appearance from 
the rest. In one specimen the last whorl has three equidistant keels—in 
the other the hinder keel is prominent, and there are three close, slight 
keels in front. There was a fragment of a shell brought from the same 
place with the former, which is deeply spirally striated, longitudinally 
plaited, and slightly keeled like the former, but it is rather more solid, 
more deeply striated, and the whorl has an extra strong prominent keel 
just before the suture, which gives the shell a very different appearance. 
I am inclined to consider it only a variety of this species. (Gray.)
