The ovate, conical shell is very pointed at its summit. It is pale red, often ornamented, with longitudinal waved and distant bands. Sometimes elongated spots appear upon the whorls of the spire, which are eight or nine in number,; the lowest are convex. The base of the shell is marked with very fine, and very approximate striae. The ovate aperture is elongated, of a whitish color. The outer lip is rounded and striated internally. The columella is arched and smooth[3]
