The genera of Australian buliniform planorbids have been examined anatomically and their classification reviewed. The major conclusions reached are: 1. Isidorella is not congeneric with Bulinus and is an endemic Australian genus; 2. Iredale's genera Lenameria, Tasmadora and Mutalena are synonyms of Physastra Tapparone-Canefri which, in turn, is a synonym of Glyptophysa Crosse. Glyptamoda Iredale is also a synonym of Glyptophysa; 3. Oppletora Iredale, synonymised with Bulinus by Hubendick, is actually related to Glyptophysa and is placed in a separate subgenus; 4. Ancylastrum Bourguignat has been examined and the results confirm Hubendick's opinion that this limpet-like genus is related to Glyptophysa. Two species can be separated by simple anatomical characters; 5. The genus Bayardella Burch includes two species, B. johni and B. cosmeta, the latter once considered to be a species of Glyptophysa; 6. Amerianna Strand includes species with either a terminal or lateral pore on a simple pendant penis; 7. A new genus Leichhardtia is erected for the northern species Bullinus sisurnius Hedley 1918.
All these genera are placed in the planorbid subfamily Bulininae.
