The aperture is less than half the length of shell, longer than wide, ovate.

[3] The central tooth of the radula has a body with broadly expanded supporting wings, a narrowed peduncle or neck, which bears a simple cusp.

The lateral teeth number five on each side and have as peculiarity that they increase in size from the inner to the outer one.

The inner lateral is slender, narrowed toward the cusp, like the centrals, and (sometimes at any rate) bearing a lamella behind the peduncle.
