The shells described and figured by Professor G. O. Sars as B. 
harpularia and its variety, rosea, do not appear to me to be identical 
with the true 5. harpularia. His shell has a different aperture, the 
whorls are more decidedly and squarely shouldered and the ribs 
fewer and more distant. It is possibly the shell mentioned above as 
probably B. Woodiana.

Shell elongated, witha long, tapering, acute, somewhat turreted 
spire. Whorls nine, somewhat convex, shouldered obtusely at some 
distance below the suture; the subsutural band is rather wide, and a 
50, 1841; Boston 
little convex, sloping gradually to the obtuse shoulder, which is an- 
gular and more or less carinated on the upper whorls, but usually 
rounded and not at all carinated on the lower ones. Suture well- 
impressed, more oblique than in most species. The ribs on the 
body-whorl vary from 18 to 21; they are stout, prominent, broadly 
rounded, separated by concave grooves of about the same breadth, 
strongly flexuous, with a sigmoid curvature at the shoulder, less 
prominent and decidedly excurved in crossing the subsutural band; 
anteriorly they fade out before reaching the base of the canal. Coarse 
spiral cinguli cover the whole surface, except the subsutural band, 
on which they are usually few and faint, or absent; the cinguli are 
broad and separated by narrower furrows, or incised grooves, which 
are made wavy by the distinct lines of growth; on the body-whorl 
there are about 12 to 14 of the spiral grooves, between the shoulder 
and the base of the canal; the cinguli become coarser, with deeper, 
wider and more distant grooves anteriorly, toward the base of the 
canal, but on the latter they become finer and closer; on the penul- 
timate and next preceding whorls there are about 5 or 6 spiral 
grooves visible. The spiral grooves are usually fainter in crossing 
the ribs, and in specimens somewhat worn they often do not show at 
all on the ribs; but on very fresh specimens they are usually per- 
fectly distinct on the ribs. 
The apical whorls are very prominent with deep, oblique sutures, 
the first nuclear whorl is angulated, apparently, from its origin, by 
two spiral lines, which quickly become raised, spiral carine; on the 
Trans. Conn. AcapD., Vou. V. 57 May, 1882.
