[edit] Distribution
Members of this genus are found in southeastern Australia and New Zealand.
[edit] Description
The shells are small, globose, subglobose or turbinate, typically polished with weakly incised spiral grooves, but the sculpture is often much stronger, with spirals and axials in a fenestrate pattern. A conspicuous plait borders the narrow umbilicus, and terminates in a distinct notch in the basal lip. The operculum is chitinous, circular and multispiral, with a central nucleus.
