Abstract
Three new species of the genus Trilemma (family Aporrhaidae), T. polivnense Blagovetshenskiy, sp. nov., T. kremenkense Blagovetshenskiy, sp. nov., and T. tenuicarinatum Blagovetshenskiy, sp. nov., from the Lower Cretaceous of the Volga Region near Ulyanovsk are described. The data on the stratigraphic range of these species are provided.
