The shell of this species is small for the genus (maximum length 30 mm) and subfusiform. The spire is moderately high, consisting of one and one-half nuclear whorls and seven weakly shouldered postnuclear whorls. The suture is entirely obscured by the subsequent whorl. The body whorl is large and fusoid. The aperture is ovate, with no perceptible anal sulcus. The outer apertural lip is weakly erect. The columellar lip is adherent to barely erect. The siphonal canal is broad, fused in mature specimens, and bent to the right and dorsally.
The body whorl bears three broadly winged varices, these extending from the suture to a point near the tip of the canal, without a break or indentation. Additional axial sculpture consists of a single large tubercle at the shoulder margin, midway in each intervarical space. Spiral sculpture consists of barely discernible cords ending in tiny, dorsally recurved points at the varical margin. The uppermost portion of the varix forms a large, broad, posteriorly hooked spine, this having, on its ventral surface, the overlapping, tightly appressed, folded-over layer typical of the genus.
Shell color is pale brownish-pink, with several gradually weakening red-brown spiral bands, these persisting at the leading edge of each varix. The aperture is porcelaneous white.

Known at present only from Loreto Channel, Baja California, and off Secas Island, Panama.
