A Monograph Of The Land Shells Of Tasmania

Excerpt from A Monograph of the Land Shells of Tasmania Describe several new species, but I have been careful not to name a shell unless it presented constant characters by which its specific distinction is well marked, and by which it may be recognised by conchologists. I consider the correcting of one error far more praiseworthy than the creating of many new species without good reason and careful investiga tion. I quite agree with the learned botanist Sir J. D. Hooker, that the naturalist who has the true interests of science at heart, not only feels that the thrusting of an uncalled-for synonym into the nomenclature of science is an exposure of his own ignorance, and deserves censure but that a wider range of knowledge and a greater depth of study are required to prove these dissimilar forms to be identical, which any superficial observer can separate by words and a name.

This was the first comprehensive work on the Tasmanian non-marine molluscs in which every species is described and illustrated. This handbook is intended to provide field keys to the identification of land and freshwater molluscs in Tasmania and to make available in one volume a checklist, with illustrations, of that fauna. Species inhabiting the littoral fringe have been included as many localities where these can be found have the general appearance of being non-marine. It is a compilation, in abridged form, of the Tasmanian information in the FIELD GUIDE TO THE NON-MARINE MOLLUSCS OF SOUTH-EASTERN AUSTRALIA published by the same authors in 1979.
