Description
The size of the shell varies between 25 mm and 45 mm.
The ovate, conical shell is smooth and of a reddish brown. The spire is composed of six whorls, whose length slightly exceeds that of the aperture. The whorls of the spire are convex, bent obliquely at the suture, and marked in that part, by slightly projecting and distant longitudinal folds. The body whorl is partially destitute of them, and those which are perceptible there, are only slightly obvious upon the upper half of the side of the aperture. The aperture is ovate and smooth. The lips are whitish, of a clear fawn-color, but the depth of the cavity presents the same tint as the exterior. It is narrower towards the base, where it terminates by a shallow emargination, the edges of which are slightly curved towards the back. The outer lip is simple, sharp upon the edge and effuse. It has, towards its upper part, an oblique fold, which seems to widen the aperture, and which partially forms the obtuse angle. The columella is almost straight, shining, and of a livid color.
Distribution
This marine species occurs off the Falklands; in the Strait of Magellan; in Antarctic waters.
