Description
The size of the shell varies between 6 mm and 11 mm. The small shell is depressed and umbilicate. It is pinkish brown, gray or yellow, the ribs articulated with dots of black and white, often forming radiating lines above, zigzag beneath, where yellow replaces pink in the ground-color. The

The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk.

is obtusely angular at the periphery. Its upper surface is encircled by 4 coarse, somewhat beaded lirae, the upper two contiguous, the third separated by wide intervals above and below it, the fourth peripheral, usually formed of two ridges close together. The interstices bear numerous fine spiral striae and sharp microscopic incremental striae. The convex base is concentrically sculptured with numerous (6 to 9) smooth striae, in the intervals between which very numerous microscopic striulae revolve. The rounded
aperture
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane.

is oblique. The outer and basal margins are thickened and very minutely crenulated within. The
columella is oblique and not tortuous above, nor entering the
umbilicus, but inserted upon its side. The front edge is nearly straight, denticulate at the base. The wide umbilicus is not very deep, its margin somewhat denticulate.
