Description

The length of the shell between 12 mm and 24 mm. and is 16 mm to19 mm wide. The conoidal shell is imperforate or narrowly perforate. It is very thick and solid, cinereous. The color of the shell is yellowish or green. It is longitudinally marked with rose-red lines, often oblique or broken into square dots. The spire is more or less elevated. Its outlines are rather convex. The six whorls are encircled by numerous lirulae, the upper ones flattened. The sutures are slightly impressed, but scalariform specimens with deep sutures are frequent. The body whorl is rounded at the periphery and on the base. The aperture is rounded-quadrate. The outer lip is bevelled to an edge, very thick and smooth within. The pearly columella is straightened in the middle. The umbilicus is narrow or concealed.
