The shell is of moderate size for the genus (maximum length 22 mm) and lanceolate. The spire is high and acute, consisting of two and one-half nuclear whorls and six or seven moderately dorsoventrally flattened postnuclear whorls. The suture is impressed but is largely obscured by varical buttresses. The body whorl is of moderate size (about one-half of the total shell length) and fusoid. The aperture is ovate and moderately large for the genus, with a barely perceptible anal sulcus. The outer apertural lip is strongly thickened and somewhat flaring, its interior bearing a series of five weak denticles, these diminishing in strength posteriorly; the uppermost denticle, interior to the shoulder margin, is generally obsolete. The columellar lip is smooth and entirely adherent. The siphonal canal is moderately long, narrowly open, bent slightly to the left, and dorsally recurved.
The varices are eight on the early whorls, diminishing in number to two or three on the body whorl. In unusual specimens as many as six of the eight original varices arc persistent in the form of more or less prominent axial costae. Spiral sculpture consists of five cords on the body and three or four finer cords on the canal.
The shell is translucent white, with brown bands, the upper portion of the body entirely suffused with red-brown; the remaining three spiral cords are also red-brown, but the interspaces arc white. A thick, flat-white, axially striate intritacalx covers the shell when not eroded; fine spiral tunnels honeycomb the intritacalx, and these arc apparent as it erodes along fine spiral tracks. In specimens in which the axial costae are persistent on the body whorl, the intritacalx follows the costae to form erect lamellae on the canal.
