Freshwater Molluscan Shells

Australian Region hydrobiidae s.s. Many species have been found endemic to the large springs of Queensland's Great Artesian Basin and elsewhere, where they are threatened by pumping of the aquifers for irrigation.

Pomatopyrgus antipodarum (Gray, 1843), New South Wales. Wood and Duke, (2001) indicate that this New Zealand species is also introduced and invasive in the Snake River of western North America.

Glacidorbis sp. New South Wales.   Glacidorbis hedleyi Iredale,
1943, New South Wales. The
white inner lip of one specimen
makes it appear detached from the
previous whorl.

Glacidorbis was originally described as a genus of the pulmonate basommatophoran Planorbidae by Iredale, 1943. In 1975, Meier-Brook and Smith re-classified them as gilled prosobranch snails after describing additional species, and their close relations to a species living in southern South America. More recently, Ponder (1986) has re-assigned the genus Glacidorbis to its own family and superfamily within the Basommatophora! Meier-Brook and Smith describe them as native to lakes and streams of mountain areas.
