.4. E. Verrill — Catalogue of Marine Mollusca. 473 
sent to me by Dr. A. S. Packard, Jr., as B. turricula and B. outer i- 
cana. 
This species is one of the several shells that have usually been con- 
founded under the name of B. turricula. The latter is European, 
and apparently does not occur on our coast.

Plate XLIII, figure 14. Plate LVII, figure 9. 
Shell solid, regularly fusiform, with a moderately high, acute spire. 
Whorls seven, with a sloping subsutural band, and the shoulder 
obtuse and scarcely carinated ; the shoulder is farther in front of the 
suture than in the three preceding species, less raised, and not so 
abrupt; the whorls are flattened, but yet slightly convex in the mid- 
dle. About 18 to 20 rather close, broadly rounded ribs cross the 
lower whorls; the ribs are separated by concave interspaces of about 
the same breadth, and are only slightly bent; at the shoulder they 
are more prominent and a little thickened ; on the upper whorls often 
slightly nodulous ; on the subsutural band they become fainter and 
are a little excurved ; they fade out below the middle of the body- 
whorls. Fine, close, wavy, raised spiral lines, or cinguli, cover the 
entire surface, crossing equally the ribs and the interspaces; they 
are coarsest and most distinct on the middle of the whorls, becoming 
much liner and more wavy anteriorly, toward the base of the canal, 
and posteriorly toward the shoulder; on the subsutural band they 
are very flue and regular. The apex is acute and compact ; the tirst 
nuclear whorl is very small, not prominent, smoothish ; the second 
has at first two and then three thin carina* ; tablets begin on the next. 
Aperture narrow-elliptical, scarcely angulated. Outer lip broadly 
rounded, with a broad and very shallow, posterior sinus, and incurved 
at the base of the canal, which is short, straight, and narrow. Colu- 
mella sigmoid. 
Color, usually pale reddish brown, or rosy, with the anterior part 
of the body-whorl and canal whitish; often entirely white or yellow- 
ish white; sometimes yellowish brown.
