Contributions for a systematic catalogue of the aquatic shells of Tasmania - Part One

Abstract

I purpose in a series of papers revising the somewhat large amount of work that has already been done, recording omissions, and describing newly discovered species and varieties of the fresh water shell-bearing mollusca of this island, preparatory to the compilation of a systematic catalogue in which the groups will be defined, the specific characteristics explained and geographical distribution recorded. Such a catalogue carefully criticised with the necessary bibliography will, I think, supply a desideratum much required by the general collector and may also be of service to the more philosophical student. Includes illustrations.
