Description
The height of the shell attains 59 mm, its diameter 25 mm.This imperforate shell is elongated ovate, solid, smooth, and glossy, with a sulfur-yellow coloration. It comprises seven moderately convex whorls, slightly constricted near the suture. The body whorl constitutes nearly two-thirds of the shell's length. The aperture is ovate-lunate, somewhat angular and slightly effuse at the base. The lips are white, broadly revolute, and not flattened. The columella is white, and the callus uniting the peristome extremities, as far as visible within the shell, is pitch-black. A line of the same color, indicating a former growth stage, extends from its center across the penultimate whorl.
