Description

The shell is small to very small, with an angulated shoulder and a straight profile. Spire moderately high, clearly stepped, white with small brown dashes, the sutural ramps with very weak spiral striae. Shell in shades of white, yellow and greenish brown. There are usually three white areas; the spire and shoulder, a spiral band below the central portion of the last whorl and another one between the two previous zones; on these white bands, brown lines delimit the white areas. Between the white bands there are brownish or yellow bands, also with some irregular white blotches. Aperture brownish, with two light bands.

Radula: broad radular tooth, with the apical portion shorter than half the total length of the tooth. Serration of medium width, with 12 to 17 triangular and sharp denticles.

Discussion
