Contributions to eratoid systematics (Mollusca, Gastropoda), 2. Late Miocene Eratoidae from Sceaux d’Anjou (Loire Basin, France), with descriptions of new taxa

Species-rich, Late Miocene eratoid faunas collected at Sceaux d’Anjou (Loire Basin, France) are revised, and two new species, Hespererato marqueti n. sp. and Erato cooperi n. sp., are described. These faunas are compared with those recorded from other Neogene deposits elsewhere in the Mediterranean. Added are notes on possible evolutionary trends and migrations during the Neogene, as based on shell morphology.
