The shell is of moderate size for the genus ( maximum length 13 mm ) and lanceolate. The spire is high, consisting of one and one-half or two translucent, convex nuclear whorls and five or six dorsoventrally flattened postnuclear whorls. The suture is moderately impressed but obscured by varical buttresses. The body whorl is moderately small and dorsoventrally flattened. The aperture is moderately small and ovate, with no perceptible anal sulcus. The outer apertural lip is smooth, moderately thickened, and non-erect, its inner surface smooth. The columellar lip is smooth and entirely adherent. The siphonal canal is long for the genus, narrowly open, bent slightly to the left, and dorsally recurved. The body whorl bears two poorly developed major lateral varices, a minor varix ventral to the left major varix, and a weak costa indicating the position of a second minor varix dorsal to the right major varix. Earlier whorls show six varices of approximately equal strength. Spiral sculpture is not readily apparent, except for traces of several weak cords on the body.
The shell is translucent milk-white, covered by a flat-white, minutely axially striate intritacalx.
