On the community of species of aquatic Pulmonate snails between Australia and Tasmania

Discussion on the classification of several shells. A revision of the nomenclature of the freshwater shells of Australia is urgent, and I venture to offer my help in instituting a critical comparison of the Tasmanian species, inter se and with continental forms. For this purpose it is absolutely necessary that the collections submitted for examination be large and varied. Limnaea huonensis (Tenison-Woods). Tenison-Woods, in his paper on the freshwater shells of Tasmania (Proc. Roy. Soc, Tasmania, for 1875), describes four species of the genus Limnaea. The new locality for L. huonensis is on marshy ground, produced by the issue of freshwater from beneath the sand dunes which line the margins of the backwaters of the estuary of the River Glenelg. Amphipeplea papyracea. Reference—Limnoea papyracea—Tate, Trans. Roy. Soc, S. Aust., vol. iii., p. 103, t. 4, f. 5, 1880. Amphipeplea papyracea —Tate, id., vol. iv., p. 140, 1881. A. papyracea was originally described from dead shells obtained from a dried pool at Penola, S. Australia, but a year later it was taken alive in the reed beds, near Adelaide, and a study of the animal brought about the new generic appellation. Gundlachia petterdi (Johnston). Locality-the hill-streams of the Mount Lofty Range, near Adelaide
