A. E. Verrill — 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).

 Shell thin, white, with a high, acute spire and strongly carinated 

 whorls. Whorls seven to eight, strongly convex, angulated by the 

 sharp revolving carinse, 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 betvveen the first and 

 second carina. On the last whorl there are usually two or more 

 similar, but somewhat less prominent, carinse 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 

 cariniB. 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 carinse. 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.
