Diagnostic Notes
The shell of this species is an unusual shape for a helicid, elongatedly conical, 10 to 20 mm high, with a width of only 4 to 7 mm. The spire tapers regularly, but ends in a blunt tip. The oval aperture has a thin lip, and the narrow umbilicus is almost covered.

The shell is very variable in color and markings, often having a cream or off-white background with many pale brown blotches, which are sometimes organized into spiral bands. The shell is often streaked across the whorls with brown. There are sometimes two spiral bands of dark brown or black, which are frequently reduced to only one band, restricted to the body-whorl. Sometimes there are no bands at all.

This species does well on sandy calcareous soils, and often prefers a coastal setting such as sand dunes. It aestivates by attaching itself to vertical surfaces such as fence posts, tall weeds and so on.
