On a new reversed Tasmanian Helix: Helix weldii

A very few years ago the island of Tasmania was regarded as being poor in land shells, but thanks to the zeal and activity of many naturalists, especially Messrs. Legrand, Atkinson and Petterd, the number of species brought to light is now very large. If the island cannot take a leading position for the number and peculiarity of its forms it has by no means an insignificant one. Up to a recent period the description of the species were scattered over an immense number of scientific works according as they had been described by various observers in different countries.
