Off the coast of Long Island, in 46 fathoms (Stimpson). Massachu- 
setts Bay to Labrador; in Casco Bay and the Bay of Fundy not uncom- 
mon in 18 to 60 fathoms. Greenland (Moller). Finmark (Lovén). 
Fossil in the Post-Pliocene deposits of Canada, Labrador, Great Britain, 
and Seandinavia. 
The identification of this species with the Buccinum pyramidale Strom, 
is somewhat uncertain; if correct, the latter name has priority.

Verrill,. American Journal of Science, vol. tii, p.210,1872. Pleurotoma cerinum 
Kurtz and Stimpson, Proceedings of the Boston Society of Natural History, 
vol. iv, p.115, 1851; Stimpson, Shells of New England, p. 49, Pl. 2, fig. 2, 1851. 
Shell elongated, fusiform, rather acute at apex, composed of about 
seven whorls; apical whorls smooth, the others angulated in the middle 
and decidedly flattened just below the suture; suture distinct, but 
shallow, undulated ; the body whorl has about eleven prominent, longi- 
tudinal, sub-acute plications or ribs, separated by wide, concave inter- 
spaces. The ribs are most prominent at the angulation above the middle 
of the lower whorl, and do not extend on the flattened sub-sutural band. 
The whole surface is covered by fine, raised, revolving lines, often 
alternately larger and smaller, separated by wider strize, and crossed by 
fine, distinct lines of growth, rendering them slightly nodulous. The 
revolving lines are most distinct on the sub-sutural band, and are often 
nearly obsolete over the summits of the ribs. Outer lip acute, with a 
decided angle at about the posterior fourth, where it recedes to form a 
decided, rounded notch, at and just above the angle; middle portion 
nearly straight, gradually curving and receding toward the anterior end; 
canal short, straight, and somewhat contracted. Color whitish, or 
slightly yellow; inner surface light wax-yellow. Length, 6.5"™; breadth, 
amm. length of aperture, 3™™.
