The shell is tiny (ca. 6 mm in length) and roughly fusiform. The spire is high and acute, consisting of one and one-half or two nuclear whorls and three or four shouldered postnuclear whorls. The suture is impressed. The body whorl is of moderate size and fusoid. The aperture is of moderate size and ovate, with no perceptible anal sulcus. The outer apertural lip is not markedly thickened and is fluted, the high points reflecting the spiral sculptural cords. The columellar lip is smooth and adherent. The siphonal canal is short, open, and bent to the left.
The shell is nonvaricate. The body whorl bears seven moderately strong spiral cords: three on the shoulder, three on the body, and one on the canal. Numerous fine axial ribs are apparent between the cords, each causing a swelling as it traverses a cord; the effect is latticelike, with a predominant spiral sculpture.
Shell color is uniform waxy yellow or orange, with a white aperture and protoconch.
Known to us from various South African localities ("the Kowie" [= Port Alfred], Jeffreys Bay, Agulhas Bank, St. Francis Bay, and Algoa Bay).
