Description The height of the shell attains 16 mm, its diameter 13 mm. The rather thick, very narrowly perforate shell has a conical shape. It contains 7 to 8 planulate whorls. The first one is eroded, the succeeding are whitish-ashen, radiated with narrow, close and flexuose blackish and violaceous lines. They are spirally cingulate, with 6 lirae on penultimate whorl. The body whorl is subangular, a little depressed above, dilated in the middle. The base of the shell is convex and ornamented with about 8 lirae. The aperture is rhomboidal. The lip is simple. The truncate columella is truncate below.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia (described as Cantharidus flindersi)
