The Polyplacophora of Tasmania

Recent dredgings and other excursions in connection with the Tasnianian Field Naturalists Club, but more particularly an extensive examination of the North-West Coast by W. G. Torr, have introduced us to many species not previously known from Tasmania. In addition, much knowledge has been acquired respecting the distribution of forms already recorded, so that the time seemed opportune to bring out a new and up-to-date list, which we believe will be of distinct value to students of this interesting group. We have here increased the Tasmanian list to 32 species, including two new ones. It will be noticed that on comparing our list with previous ones, several names disappear, either because we consider there was a wrong identification, or because we cannot confirm the record, believing that a mistake was made.
