Title: A new euomphalomorph gastropod genus in the faunula, listed by Vadász (1915) from Alsórákos (Perşani Mts, Romania; ?Early Jurassic)

Abstract: Five species are distinguishable from the available, most probably Early Jurassic material, consisting of a few poorly preserved inner casts and a specimen with shell. The latter one preserved also the original shell microstructure that was different from that of the comparable genera just like some of the megascopic characters. These gave a basis for establishment of Valamidiscus persanyensis n. gen. & n. sp. Short descriptions of the steinkerns are also given in the systematic part of the paper. Because Valamidiscus n. gen. cannot be fitted into the existing families without objection, its accommodation has been tentatively chosen (?Discohelicidae, ?Cirroidea).
