Middle Miocene (Badenian) gastropods from Korytnica, Poland; Part II

Abstract

This report is the second part of the monograph of the surprisingly rich assemblage of gastropods occurring in the Middle Miocene (Badenian), so-called Pleurotoma Clays in the environs of Korytnica in the Holy Cross Mountains, Central Poland. Presented are new data on the age of the Korytnica Clays, that involved an adjustment in the title of this monograph. Reviewed is also an updated state of recognition of the associated fauna, both invertebrates and vertebrates. The systematic account contains a description of 135 prosobranch species of the ten superfamilies: MelaneIlacea, Hipponicacea, CaIyptraeacea, Strombacea, Cypraeacea, Triviacea, Naticacea, Tonnacea, Muricacea, and Buccinacea, without Nassariidae. Within this assemblage, 11 species are new for the science (including 2 species formerly reported from Korytnica, but determined erroneously), and the other two require to be labelled as a nomen novun; of the recognized as many as 90 have not hitherto been known from Korytnica and 83 from the Miocene of Poland. As new species established are: Leiostraca jaskiewiczi sp.n., Melanella (Polygyreulima) sanctacrucensis sp.n., Melanella (Polygyreulima) korytnicensis sp.n., Melanella (Polygyreulima) montilysensis sp.n., Megalomphalus convictor sp.n., Nacca unica sp.n., Hadriania polonica sp.n., Magilus? ficiformis sp.n., Coralliophila (Coralliophila) serraticincta sp.n., Pyrene (Mitrella) korytnicensis sp.n., and Cantharus minutulus sp.n. For two taxa at the species level the new names introduced are: Purpura (Tritonalia) kojwndgievae nom.n., and Euthria friedbergi nom.n.
