Sculpture of about 15 steeply rounded primary spiral cords, subequal and evenly spaced anteriorly and posteriorly, alternatingly larger medially; rarely with secondary spiral cords. Interspaces flat. Axial sculpture absent except growth lines. Colour maculated black and cream. Apertural margin of columellar callus with strong anterior tooth, weaker medial tooth, and strong posterior bifid tooth; other teeth possibly present posteriorward. Abapertural portion of columellar callus with six well-spaced transversely elongate teeth, not aligned with apertural teeth; no papillae present. Outer lip with posterior inner edge bevelled and fluted; inflexions of bevel with small, spirally elongate spirally denticles along entire length. Base of columella separated from basal portion of bevelled outer lip by shallow sulcus.
