(Original description) Animal: The foot is fuscous olive, large, thick, square in front, pointed behind.

The eyes are large and black, on the upper outer side and at about a fourth of the length of the tentacles, which are rather solid, long, and cylindrical.

Spirals — there are many fine, irregular, and unequal rounded striae, which faintly appear on the surface, but are distinct on the columella and front of the shell.

The colour of the shell is white, with a faint tinge of yellow, horny, translucent, with a smooth and shining, but hardly glossy, surface.

The body whorl is large and tumid, with a protracted rounded base cut off on the left by an oblique, scarcely concave line.

The outer lip shows a semicircular curve in both planes, leaving a shallow, wide, shortly rounded sinus between the lip-edge and the body.
