Description

The height of the shell reaches 6.2 mm. The elongate shell has a pointed ovate shape. It is thin, smooth, and shining. The spire is conic. It contains about 5 rather convex whorls, separated by well impressed sutures. The acute apex is rose colored. The oval aperture is oblique. The outer lip is thin and translucent. The columella has a white callus which is somewhat distended at the slightly impressed and grooved subperforate or imperforate umbilical region. The color of the shell is white, yellow or pale rose, more or less clouded longitudinally with rose, orange or brown, sometimes only with subsutural and peripheral series of short flammules, the entire surface closely and regularly punctate with pink or orange, and white.
