[Proc. Eoy. Soc. Victoria, 18 (N.S.), Pt. II., 1905]. Art. VI. — Catalogue of tJie Marine Shells of Victoria, Part IX.; WitJt complete Index to the whole Catalogue. By G. B. PRITCHARD and J. H. GATLIFF. [Read 14th December, 1905.] The present part includes additional notes and references on the species already referred to by us, together with corrections and alterations, as well as particulars on additional species which have been obtained since the publica.tion of the various parts. The additional species here dealt with number 58, so that with the previous total of 707, our list of Victorian Marine Shells now amounts to 765 species. An Index to the whole catalogue is appended, giving refer-ences to the genera and species, but not to the sub-genera, and we have to thank Mr. R. A. Baistow for its compilation. We would draw attention to a recent paper by W. H. Dall, entitled " An Historical and Systematic Review of the Frog Shells and Tritons," published by the Smithsonian Institution, Volume xlvii., 1904, pp. 114-144, in wliich he re-classities the shells which we have regarded as being comprised in the family Lotoriidae, and refers to some of our species.
