The shell is ear-shaped, with a minute spire and a very large, convex body whorl.

Its surface is somewhat shining, black with scattered whitish dots, spots or zigzag lines.

The shell is sculptured by numerous close microscopic spiral striae, several smaller alternating with larger ones, and somewhat decussated by impressed growth lines.

The ovate aperture is angled above, polished, and bright inside, and of a blue color.
