The shell is of moderate size (maximum length 40 mm) and fusiform. The spire is high and acute, consisting of one and one-fourth smooth, tabulate nuclear whorls and six to eight angulatc postnuclear whorls; the apex of the protoconch is de-pressed and canted opposite to the cant of the postnuclear whorls. The suture is weakly defined. The body whorl is of moderate size. The aperture is of moderate size and ovate, with a broad, very shallow anal sulcus. The outer apertural lip is non-erect and finely, marginally crenulate; its inner surface bears five moderately weak denticles, these increasing in prominence anteriorly. The columellar lip is adherent above, detached and weakly erect below; on the columella, immediately above the canal, is one weak, knoblike denticle. The siphonal canal is moderately broad and open, comparatively short, and dorsally recurved at its end.
The body whorl bears seven spinose varices. Intervarical axial sculpture is lacking. Spiral sculpture consists of four scabrous major cords alternating with minor cords. Spiral sculpture is lacking on the shoulder. Where the spiral elements intersect the ventrally fimbriate varices, short to moderately long, essentially straight, closed, medially grooved spines are developed.
Shell color is yellow-brown to dead white. The aperture is entirely porcelancous white.
