The recent mollusca of Tasmania

Tasmania may be considered fairly rich in recent molluscan species, as she possesses nearly 700 marine forms, with about 100 terrestrial and fresh-water kinds besides.
Very many of the species in all branches are extremely small, requiring much careful search in order to obtain them, and microscopical examination to reveal their characteristics, their beauties of form, sculpture, and colouring.
But such work is well repaid by the results, whilst, doubtless, there are still various species to be discovered in the less well-known parts of the island, for many of the recognised forms are very local in their habitats, and, in numerous cases, their minuteness renders them so difficult to find that even an experienced collector may overlook them.
