A revision of the Australian species of Rissoellidae (Mollusca: Gastropoda)
Abstract
The Rissoellidae is tentatively included in the Heterogastropoda. The 14 Australian species and subspecies of Rissoella, 11 of which are new, are separated into 4 subgenera. Their known distributions, radulae and opercula, and in some cases the external features of the animal, are described. A key to the Australian species is given.
