This genus is endemic to New Zealand.

[edit] Description

The shells are small, ovate-conical, white, smooth and shining. Sculpture consists of a few distinct incised spirals around the lower base, and sometimes a zone of weaker spirals on the upper base as well.

The radula has a central tooth bearing about 10 long denticles, laterals one to three with seven or eight similar long denticles, the fourth lateral with a few denticles, and the fifth lateral finely serrate only. The marginals are numerous, long, slender and hooked.

The operculum is circular, closely spirally coiled, thin and yellowish.
