Fossil and recent Lutraria (Mollusca, Bivalvia) in Europe, with descriptions of four new species

Miocene to Recent European Lutraria material in several Dutch collections was systematically revised. Ten species could be distinguished, viz. Lutraria angustior Phihppi, 1844 (? Pliocene/? Early Pleistocene to Recent), L. expansa Dollfus, Berkeley Cotter & Gomes, 1903 (Miocene to ? Pliocene), L. frangula n. sp. (Miocene), L. latissima Deshayes, 1831 (Miocene), L. lutraria (Linné, 1758) (Pleistocene to Recent), L. magna (da Costa, 1778) (Miocene to Recent), L. obliqua n.sp.(age unknown, but probably Late Holocene), L. procera n.sp. (Pliocene), L. scaldensis n. sp. (Pliocene) and L. vindobonensis Sacco, 1901 (Miocene). Six species (angustior, frangula, lutraria, magna, obliqua and scaldensis) are known from the Netherlands.
