Art. XIX. — Catalogue of the Marine Shells of Victoria. Part VI. By G. B. PRITCHARD and J. H. GATLIFF. [Eead 9th October, 1902.1 The present paper refers to one hundred and twelve species, contained in the following families : — Stomatiidae, Haliotidae, Pleurotomariidae, Fissurellidae, Patellidae, Lepidopleuridae, Ischnochitonidae, Mopaliidae, Acanthochitidae, Cryptoplacidae, Chitonidae, Tornatinidae, Scaphandridae, Bullidae, Akeridae, Ringiculidae, Philinidae, Aplysiidae, Pleurobranchidae, Umbrel-lidae, Siphonariidae, Gadiniidae, and Dentaliidae. The previous papers, Parts I. to V., dealt with 419 species, so that with the present additions the total number of species now dealt with amounts to 531. We have omitted from present consideration our representa-tives of the families Truncatellidae, Auriculidae, and Amphi-bolidae, as they are not strictly marine forms. The present part concludes the Gastropoda and Scaphopoda, with the exception of some species which have been obtained and identified subsequent to the publication of the various parts to which they belonged ; these will be included in an appendix at the end of the treatment of the Lamellibranchiata. Subsequent to the reading of our last paper. Professor Tate and Mr. May published a Revised Census of the Marine IMollusca of Tasmania, in which they deal with 679 species, including the Palliobranchiata and brackish water forms. We do not agree with all their conclusions, and will take an opportunity later on of discussing the points on which we differ. Family Stomatiidae. Genus Stomatella, Lamarck, 1809.
