A revised list of the exotic land molluscs of Tasmania

The Tasmanian exotic land mollusc fauna is reviewed including the revision of names and the addition of recent records. The fauna includes 28 species introduced since European settlement, of which one has not been recently recorded. Notable recent introductions include Cernuella virgata (Da Costa, 1778) and Arion ater Linneaus, 1758. The taxonomy of the genus Paralaoma, which includes both exotic and native species, is discussed. The first Australian record of Arion silvaticus Lohmander 1937 is published. Introduced carnivorous Oxychilus species are a probable threat to some native land snail species.
