Description
The length of the shell varies between 5 mm and 25 mm. The hemispherical shell is smooth, depressed, convex above and flattened beneath. The blunt spire is formed of four indistinct whorls, entirely smooth. The aperture is ovate, reddish, rather small and obliquely emarginated. The outer lip is smooth and slightly margined. The columella is arcuated towards the middle, furnished with a wide, reddish, and almost circular callosity, which extends upon the body of the body whorl. The coloring is slightly variable, it is generally of a yellowish or reddish white, with brown lines, and two decurrent, interrupted, or articulated bands, one of which surrounds the suture, and the other only borders the circumference. The epidermis is thick and brown. Distribution
This species occurs in the Mediterranean Sea and in the Black Sea. References
