Notes on the Cretaceous invertebrate faunas of Portugal I: a new species of Anadromus (Mollusca, Gastropoda) from the Campanian-Maastrichtian of Taveiro (Coimbra, West central Portugal)

A new species of terrestrial gastropod - Anadromus penai sp. nov. (Fam. Anadromidae) - is described from a set of composite moulds collected in reddish silts and clays of Campanian-Maastrichtian age, found in the lower pan of the Taveiro Formation (Taveiro, Coimbra, West Central Portugal). The known occurrences of this new species are restricted to the type locality. The main differences from other contemporaneous Anadromidae are the profuse spiral sculpture of the body-whorl, with 20-22 sub-equal, close, and regular ribs.
