Contributions to eratoid systematics (Mollusca, Gastropoda), 3. European Oligocene Eratoidae, with description of a new species

European Oligocene eratoid faunas are revised systematically and compared with assemblages recorded from elsewhere. The material comes from the Lower Oligocene (Rupelian) of Gaas-Espibos (France), the Upper Oligocene (Chattian) of Abbesse (Aquitaine, France) and the Upper Oligocene (Kasseler Meeressand, Chattian) of Glimmerode (Germany). One new species, Erato dolini n. sp., is described, and possible evolutionary trends and migrations, as based on shell morphology, are outlined.
