Description
[edit]Original description: "Shell small, solid with an elevated spire of about 6 whorls, the first 2 forming a relatively large, blunt nucleus. The body-whorl is fairly large, convex. Sutures are narrowly grooved with a slightly appressed margin in front. Parietal callus narrow and extends to the end of aperture. The pillar structure forms a small, double fold at the end of the pillar, often much heavier within; opposite to it at the lower end of the outer lip, there is sometimes a small liration. Inner wall of the pillar shows no sign of corrosion, its form being normally concave. Surface smooth and polished, white or yellow, sometimes with longitudinal streaks or flammules of brown. Lip simple and unthickened. Length 11 mm., diameter 5 mm."[3]
