| Abstract: | Two new species of fossil freshwater gastropods, Borysthenia intermedia sp. nov. and Tanousia krasnenkovi sp. nov., from the Tiraspol deposits of the Middle Pleistocene of the Oka-Don Plain are described. Parafossarulus priscillae (Girotti, 1972), Viviparus diluvianus (Künth, 1865), and Lithoglyphus jahni Urbasnski, 1975 are reported from Russia for the first time. The status of some problematic species of freshwater gastropods from the Middle Pleistocene of the region studied is discussed. The chronological and environmental significance of all gastropods studied is given. |
