The small, spindle-shaped shell has a chestnut color. It is covered with numerous fine, transverse striae. It contains nine slightly convex whorls to the spire, the upper longitudinally plaited. The sutures are pretty apparent, edged with small black and white slightly elongated spots. The brownish aperture is narrow and ovate. The outer lip is thin and delicately striated within. The columella is slightly arcuated and smooth, forming a small siphonal canal, emarginated at its base.
