Cantharidus antipodum

The base of the shell is slightly convex and impressed in the middle.

The shell is subperforate or imperforate and contains a few distant fine spiral lirae, visible only under a good lens, more distinct on the base, and very fine close growth lines.

The large aperture is round, acute on the left, and with a flat border on the right margin.

The umbilicus is only indicated and nearly covered by the convex, sharp outer lip.

The columella is subvertical, arcuate, simple, slightly expanded and nearly covering the umbilicus.

The small, imperforate, thin, fragile shell has a globosely conoidal shape.

Others have a pinkish ground colour, with darker markings between the principal bands.

The columella is subvertical, semicurved, expanding as a callus over the umbilicus.
