Often this coloration is arranged spirally in the form of indistinct chevrons. The shell is solid with a long, narrow aperture and is shaped like a small helmet shell. The aperture is bordered with whitish raised lirae which appear as teeth on the inside of the thickened outer lip. The outerlip is crossed by orange bars that coincide with dark brown markings on the dorsal side. The parietal shield is glossy and rounded. It is yellowish and overlaid with three or four orange patches, one of which is always loated at the apical end. Sculpture consists of narrow axial ridges that are depressed by shallow spiral grooves to form axially elongate beads.
