Shell about 9 mm. (0,375 inch) in length, elongate, imperforte, and strongly sculptured. Whorls 11, rather strongly convex. Nuclear whorls 3, smooth and pale amber in color. Color a pale and dull brown. Suture deeply impressed. Aperture subcircular. Outer lip much thickened and rounded. Columella short and arched. Axial sculpture consisting of 10 strong costae, the ends of which produce crenulations at the suture. Spiral sculpture consisting of 8 or 9 cords which are strong but much less so than the axial costae. Slight nodules are produced where the spiral cords pass over the axial costae. In addition there is an exceedingly fine reticulated sculpture between these costae and cords which, under 30x magnification, has the appearance of a coarsely woven cloth. This latter character is invested in the superficial layer and may be lost in worn specimens. Basal areas defined by a low, rather inconspicuous ridge beyond which the axial costae do not extend. The basal area, however, does have the fine reticulated pattern. Operculum corneous and paucispiral.

Somewhat similar to O. aurifila, this species grows to 9mm, is a pale dull brown and is found in deep water from southern Florida to Barbados. The whorls are more bulbous than in O. aurifila and feature 16 strong costae with crenulations at the suture. There are 8-9 strong spiral cords which produce nodes where they cross the costae. As in O. aurifila, there is a microscopic reticulated pattern. There is a low basal ridge marking the end of the axial costae. The suture is deeply impressed. The angle to spire is about 28 degrees. Most uncommon in collections.

Range. From off Palm Beach, Florida south to Barbados.
