Shell of moderate size, 14-35 mm., fusiform, with a tall spire of rather sagged turreted whorls, and a short body-whorl, rather quickly contracted to a moderately long to rather short slightly flexed weakly notched anterior canal. Protoconch of two depressed subcarinate smooth whorls. Adult sculpture of axial folds, spiral cords and threads; in the peripheral area, one or more of the overriding heavier spirals fuse over the axials to form low keels. Aperture narrow, with a thin outer lip, interrupted above by a deep narrow U-shaped sinus, restricted above by a moderate parietal callosity, at the termination of a prominent smooth sub-sutural fold. Colour uniformly whitish to brownish. Radula, a pair of simple slender curved non - barbed marginals (haliplexa). Range: Recent, Lower California and Central America, 10-90 fathoms and Miocene of Florida, Dominican Republic, Jamaica, Trinidad, Panama and Costa Rica. The record for the Miocene of southern India requires con¬firmation.
