This very distinct species was dredged by me several times, 
in small numbers, at Eastport, Me., in 1864, 1868, 1870, in 20 to 90 
fathoms. One specimen was dredged by Messrs. S. I. Smith and O. 
Harger, of the the United States Fish Commission, in 1872, on Le 
Have Bank, off Nova Scotia, in 45 fathoms. Off Cape Cod, 84 
fathoms, 1879. It appears to be a very rare species, however, and 
none of my specimens have the animals preserved. Greenland, —

This has not unfrequently been confounded by authors with B. 
cancellata , and perhaps with B. pyrcmiidalis. It is our most 
slender and elongated species, with broadly rounded whorls, strongly 
cancellated by numerous narrow transverse ribs and raised revolving- 
lines, or cinguli, which are about equally prominent, and form small, 
oblong nodules where they cross the ribs.

Plate LVII, figures 6, 6a. 
Shell fusiform, with a rather high, regularly turreted, acute spire. 
Whorls six or seven, strongly flattened, abruptly and squarelv 
carinate-shouldered; broadest at. the shoulder; the carina rises into 
prominent, but small nodules where it crosses the ribs. Sculp- 
ture coarse and prominent. Above the carina, or shoulder, the 
surface descends with an abrupt slope to the suture, forming a 
rather broad subsutural band, which is crossed by the somewhat 
prominent, excurved continuations of the ribs; between these are 
smooth, concave interspaces; spiral lines do not occur, unless 
very rarely and sparingly, on the subsutural band. The suture 
is rather oblique. The ribs are about 15 on the last whorl, promi- 
nent, but narrow, rather acute, with a smoothish edge; they are 
nearly straight below the carina, and gradually fade out toward the 
base of the canal; the intervals between the ribs are broad, concave, 
much wider than the ribs, crossed by well-marked, raised, spiral 
lines, which are much less elevated than the ribs, and not crowded, 
often unequal, rather stronger and more distant at the base of the
