Proxiuber is a genus of sea snails, marine gastropod molluscs in the family Naticidae, the moon shells.[2] The genus is endemic to New Zealand, with fossils dating back to the early Eocene, found in primarily in New Zealand, with one fossil species in Australia.
Members of the genus have small, solid shells, open umbilicus, and almost no funicle. Protoconches are smooth, pauciscpiral and have a large nucleus, while the operculums are smooth, shelly and have two weak marginal grooves. The radula have a tricuspid central tooth.[3] The protoconches have an flattened knob at the tip, while the funicle is either obsolete or close to being obsolete, and radula have tricuspid central marginals and bifid inner marginals.[4]
