Description The size of the shell varies between 8 mm and 20 mm.
The shell often exhibits a combination of earthy tones, such as brown and gray, with subtle patterns that blend well with its marine surrounding.
The concentric lira form thickened scales upon the costae and when a little worn out, have a bead-like appearance. The foramen is roundly ovate, small, and thickened within, with a white collar. The interior of the shell has a thin deposit of white, glossy callus, through which the external costae are visible. The dotting upon the margin is formed by the terminations of the costae.
Distribution This species occurs in the Indian Ocean off KwaZuluNatal, South Africa.
