C. testa sub-fusiformi, utrinque conicd, concentrice sulcatd, antice sub-productd, retro- 
head, emarginatd ; spird acuminatd, in longitudine trientem totius teste superanti: anfrac- 
tibus convexiusculis, sub-angulatis ; marginibus posticis angustis, concavis, concentrice 
sulcatis ; sulcis concentricis irregularibus, postice evanescentibus: apertura angustd ; labro 
aliformi, fere semicirculari, acuto, intis incrassato, antice crenulato, postice perparum brevi- 
terque emarginato ; labio antice reflexo, producto. 
Var. uEeMiuissa. Testa breviori, latiori, postice levi ; marginibus anfractuum valde 
cavatis, unico sulco concentrico exaratis. 
Shell nearly fusiform, doubly conical, concentrically furrowed, rather produced and 
bent backwards at the base, and deeply notched; the concentric furrows are irregular, 
crowded, and sharp-edged over the base, more distant and obscure as they ascend the 
shell; the spire is pointed, elevated, rather more than a third part of the whole shell 
in height, and terminates in a very small, conical pullus. The whorls are rather 
convex, slightly angulated at the shoulder, and a little thickened on the edge round 
the suture; the posterior margin is narrow, rather concave, and traversed by two or 
three deepish furrows. The aperture is narrow and nearly straight, with the anterior 
extremity slightly curved outwards and backwards; the outer lip is remarkably large, 
almost semicircular, thickened within, thin and sharp on the edge, and separated from 
the suture by a very small but rather deep curvature; the inner lip produced, reflexed, 
and curved backwards; the columella presents a broad, elevated ridge or “crest” 
in front. 
A variety occurs at Brockenhurst, in which the shell is shorter and wider; the 
posterior portion of the whorl is smooth; the angle on the shoulder sharper and more 
clearly defined, and the posterior margin more concave, and traversed by a single 
obscure furrow. 
The presence, in this species, of concentric furrows instead of the sharp, elevated 
lines which characterise C. dormitor, is not a character to which much specific value 
can be attached, as these ornaments interchange by insensible degrees; but the 
depressed, concave posterior margin of the whorls, the very large wing-like, outer lip, 
the small, narrow, but deep curvature which separates the outer lip from the suture, 
and the deep anterior notch, with its usual accompaniment, the elevated crest on the 
columella, appear to me to justify the separation of the present species. Even the 
variety which, with its half-smooth half-sulcated surface, so much resembles the var. 
seminuda of C. dormitor, is easily distinguishable by these characters.
