The shell is longitudinally grooved, and very remarkable for being furnished with numerous, rather distant, smooth, narrow, raised spiral bands; having the inter-spaces finely spirally striated; the nucleus of the shell, like that of a voluta, is mammillary.

Lamarck never having seen this shell has described it on the authority of Chemnitz, whose figure agrees very well with the shell before me; excepting that the spots round the suture form nearly a continual band at a little distance from it; the outer lip is smooth and thin; the inside dull livid brown; the axis is fourteen-twelfths, the diameter seven-twelfths, of an inch.
