Description
Size: Length 10.45-15.06 mm; diameter 5.30-7.59 mm.

The shell is small, smooth and ovoid. The spire is completely enveloped within the body whorl in the adult. The surface of the shell displays a fine gloss in fresh and unworn shells. The body whorl is elongately ovoid, being broader towards the spire than anteriorly. The aperture is narrow and elongated and the outer lip thickened and smooth within. The columella bears four oblique folds of which three upper ones are strongly developed and well separated, while the fourth is very small and only imperfectly separated from the fold next above it. Except for a somewhat broad, feebly marked dull white band on the outer margin, the surface of the shell is ornamented throughout with a characteristic color pattern of greyish brown spiral bands of varying width, decussated by fine whitish longitudinal lines on a bluish white ground.
