Original Description (from Say, 1824, p. 154):
"Covered with longitudinal, contiguous, slightly elevated, granulated striae.
Description. Shell subcylindric, contorted, inferior side flat; the whole surface is composed of very numerous, small, contiguous striae, each consisting of a single row of granules; these series are alternately smaller.
Diameter of the larger end three-tenths, of the largest specimen two-fifths of an inch.
The continuity of the tube within, is interrupted by oblique diaphragms. It sometimes approaches the spiral form, and one specimen has three complete volutions of much regularity."
