Crosseola is a genus of minute sea snails or micromolluscs, marine gastropod molluscs in the family Cyclostrematidae.
Distribution
Members of this genus are found in southeastern Australia and New Zealand.
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.
