"Whorls about seven, angular, flattened on the shoulder, which is crossed diagonally by the variceal ridges; varices about eight on the body-whorl, sub-equal, spinosely elevated on the shoulder angulation, and crossed by four sub-equal revolving ridges, which appear double on the crests of the varices; only two such ridges on the whorls above the body-whorl.
Aperture somewhat more than half the length of shell, key-hole shaped, with the canal broadly deflected. Length nearly .75 inch.
A single specimen from Ayres' pits, near Shiloh, in the possession of Miss Emma Walter, of Philadelphia"
