## Description

The length of the shell varies from 9 mm to 20 mm.
The small shell is ovate, conical, rather shining, and pointed. The spire is formed of six or seven indistinct whorls, often ornamented with longitudinal folds, which are rarely continued to the base of the body whorl, and which are crossed by very fine and slightly marked transverse striae. The aperture is white. The outer lip is thick, white externally, and denticulated within. The columella is smooth and shows two guttules at the base. The coloring of the shell is very various. The ground color is generally of a yellowish white. The transverse striae are accompanied with very fine lines, white and of a red bay color. Reddish, or bluish brown spots, intersected with white, form zones upon the upper part of each whorl. At the base, and the middle of the lowest, the brown lines are more marked.

## Distribution

This species occurs in the Mediterranean Sea and in the Atlantic Ocean off the Azores.
