Original description.
Shell elongate-conic, sinistral, flesh colored. (Early whorls decollated.) The nine remaining are moderately high, marked by a double spiral row of very strong, equally developed, rounded tubercles, which are separated on the first three turns by a channel as deep and well marked as the sutures. This space between the two rows of tubercles gradually develops into a slender tuberculate keel, which on the last turn is about half as wide as the tubercular ridges. There are about eighteen tubercles on the tiiird to seventh of the remaining wdiorls and twenty on the penultimate. Periphery angulated. Base short, marked by two strong spiral keels. (Aperture fractured.).
