A. BH. Verrilli— Mollusca of the New England Coast. 167 
Originally described from off Georgia, in 400 fathoms. According 
to Mr. W. H. Dall, it is found in shallow water on the west coast of 
Florida (Proc. Nat. Mus., vol. vi, p. 324, 1883).

PLATE XXXI, FIGURES 11, 11a, 110. 
Shell thin, white, with a high, acute spire and strongly carinated 
whorls. Whorls seven to eight, strongly convex, angulated by the 
sharp revolving carinz, of which there are usually three very prom- 
inent ones on the whorls of the spire. The upper one of these is 
situated at a considerable distance from the suture and forms a prom- 
inent shoulder, above which the surface of the whorl is somewhat 
concave and covered with several much finer, raised, spiral lines, of 
which one, usually at about the middle, is a little more prominent than 
the rest; the second carina is situated below the middle of the whorl 
and is separated from the upper one by a broad, concave interspace, 
which is covered by rather fine, distinct, raised spiral lines, separated 
by very distinct grooves of about the same breadth; the third carina 
is usually situated just above the suture, but is sometimes concealed 
by it; it is separated from the second carina by a concave, spirally 
lined interspace, a little narrower than that between the first and 
second carina. On the last whorl there are usually two or more 
similar, but somewhat less prominent, carinz below the middle of the 
whorl, and the surface is everywhere covered by regularly spaced 
spiral lines or cinguli and grooves. Aperture rather small, some- 
what semicircular; the outer lip is nearly regularly rounded from 
the suture to the base of the canal, but is slightly angulated at the 
carine. In some of the larger specimens it somewhat recedes, and is 
slightly everted just below the suture. The canal is short, somewhat 
narrowed, nearly straight, or sometimes with the anterior end a little 
everted. The columella is nearly straight, its inner margin having a 
slight sigmoid curvature; the inner lip is covered by a very thin 
coat of smooth enamel, which extends out only a slight distance be- 
yond the edge of the lip, with a broadly curved outline. The nuclear 
whorls are small and regularly spiral, consisting of rather more than 
two turns, and have the surface smooth and glossy. On the succeed- 
ing whorl there are about four distinct carine. The epidermis is 
inconspicuous or wanting. The operculum is rounded-elliptical, con- 
siderably smaller than the aperture, with the nucleus situated near 
the outer edge, in front of the middle. The animal is destitute of 
eyes; the tentacles are long, slender, and gradually tapered.
