The body whorl is very finely longitudinally striated. The narrow aperture is spirally striated behind. The columella shows four plates, the anterior one small. The outer lip is angled and deeply notched in front. The shell is blackish brown, spotted with white, especially on the spire. The interior is purplish. [2]
