The size of the shell varies between 5 mm and 13 mm. The solid, umbilicate shell has a conical shape. It is deep green, brown, pinkish or olivaceous, more or less dotted with white and a self-color, sometimes radiately flammulated with white. A tract around the
umbilicus is white, tessellated with brown. The
spire is elevated, sometimes scalariform. The
apex acute. The upper
whorls are slightly convex. The
body whorl is convex, depressed below the
suture and, rounded at the periphery. The whole surface bears numerous low, smooth spiral striae, which are often subobsolete on the body whorl, and it is then nearly smooth. The base of the shell is concave in the middle. The
aperture is rounded-quadrate, smooth within or finely lirate. The
columella is slightly sinuous, bidentate at base, expanding in a callus above, which slightly impinges upon the umbilicus. ==Distribution==
