The length of the shell attains 6 mm. (Original description) The minute shell is  fusiform, turreted, elongate and thin. It is saturated with a reddish chestnut. It contains 6 convex whorls, including the protoconch. They are spirally many keeled and between the keels thickly and slenderly longitudinally lirate. The protoconch consists of two subinflated whorls which are spirally and equally striate. The aperture is shorter than the spire, elongately ovate. The outer lip is thin and sinuous. The inner lip is inconspicuous. Distribution
