Molluskenfauna Aus Dem Burdigal (Unter-Mioz n) Von Fels Am Wagram in Nieder sterreich

The present paper describes a molluscan occurrence, rich in macrofossils, of the Burdi galian north of Fels am Wagram in Lower Austria. In the course of several years, various gentlemen and the author had collected i.a. a rich microfauna which had not yet been known to exist in the Austrian Burdigalian and which made the beds-of little local extent appear to be particularly interesting. There were established 166 species and subspecies (thereof described Lamellibranchiata: 48, Scaphopoda: 1, Gastropoda: 47), the most important of which were dipicted. A supple ment to the systematic part shows the accompanying fauna so as to furnish as complete as possible a faunal picture. As regards the Austrian Miocene there were found some new genera: Cyrtodaria DAUDIN 1799, Angulus Mergerle von MUEHLFELD 1811, Burtinella MOERCH 1861, Drepanocheilus MEEK and many new species marked with a cross (+) in the comparative list of faunas. Moreover, the following species and subspecies were newly described: Astarte (Tridonta) levigrandis nov. spec. Cardium (Cardium) ritter-gulderi nov. spec. Cardium (Cerastoderma) edule felsense nov. subspec. Cardium (Rudicardium) grande tereticostales nov. subspec. Dentalium (Antale) kickxi transiens nov. subspec.
