Extract

Shell elongated, spire composed of many convex whorls, which are very finely striated, 2 or 3 of the striæ being very distinct and wide apart in front of the sutures. The last 2 whorls have 10 or 11 and the other whorls have 14 or 16 well-marked ribs, with occasional varices. On the last whorl there is a slight angularity in place of keel. The wing exactly resembles that of A. Parkinsoni, and in this may be distinguished from that of A. Mantelli. The anterior canal is moderately long.
