Otopleura auriscati

The smooth, white, solid shell has an ovate, elongated shape.

The pointed spire is composed of ten or eleven slightly convex whorls, distinct and separated by a narrow scaffolding accompanying the suture, which is somewhat undulated.

All whorls are longitudinally ribbed, extremely regular, often terminated at their summit by a small tubercle at the sutures.

The outer lip is thick, white, forming a little gutter at the base.

The columella is imperforate at its lower extremity, oblique, bearing three unequal folds.
