Shell rather short, fusiform, and moderately compressed. Apical whorls four, subglobular and plain (fig. 5 h), constituting the opening of a very convex spiral angle; next whorl angular and costated longitudinally; the succeeding whorls of the spire (three or four) have either no longitudinals or at best very faint ones, but are spirally ornamented throughout, and betray a tendency to bicarination which varies in different specimens but is generally well marked. The body-whorl exhibits a third carina, sometimes also visible in the penultimate. The chain of bilateral varices is more or less continuous, but a spine is always sent out on both sides where the varix crosses the lower keel (fig. 5 e). The direction of the spines is irregular, those on the body-whorl have mostly a tendency to curve upwards. Aperture very nearly quadrate and graduating into a wide and straight canal. There is no actual wing, but in the well-preserved specimen, fig. 5 a, the spines are seen to be grooved, and the groove in the anterior lateral spine is seen distinctly to communicate through a notch in the outer lip with the aperture, hence it may also be said to have the function of a wing.
