The length of the shell is between 12 mm and 24 mm and is 16 mm to 19 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. ==References==
