Summary
Iredale’s higher classification of Australian land snails is reconciled to the better known classifications of Wenz and Zilch (in the Handbuch der Paläzoologie) as modified for the higher taxa by Taylor and Sohl. This classification for the endemic Australian fauna comprises two subclasses (Prosobranchia and Pulmonata. each with two orders), 14 superfamilies and 25 families (and additionally 4 superfamilies and 9 families which include the various introduced species). These higher taxa are used to classify the 204 genera and 40 subgenera of native Australian land snails as recognized by lredale, and the 21 genera of introduced land molluscs. The genera and subgenera are listed for each appropriate higher taxon, but no attempt is made to assess their validity.
