Description

The length of the shell varies between 4.5 mm and 7 mm. The shell is oblong-ovate. The sutures of the spire are rather deep. The shell is longitudinally crossed by bold, sinuous ribs, interstices between the ribs latticed with conspicuous striae. The color of the shell is white, the striae are pale brown. The white shell has a broad brown band above the aperture, reappearing on the spire, and another one at the base of the body whorl. The aperture is narrow. The outer lip runs almost parallel to the columella. Distribution
This species occurs in European waters off the British Isles and throughout the Mediterranean Sea, especially off Greece, Italy and France. . References
