●

intermedia , Bithinia (Nematura) – Deshayes, 1862-DescrCoqFoss: 513, 34, pl. 34, figs 41-43. First made available by Melleville, 1843, as Paludina intermedia (p. 96 [50, 83], pl. 4, figs 4-6). — Type locality: Ciry-Salsogne. — Type age: Eocene (Ypresian). Stenothyra intermedia (Melleville, 1843) (Wenz 1926: 2217) . — Current status: Bythinella intermedia (Melleville, 1843) ( Le Renard & Pacaud 1995: 98) .

pygmaea , Paludina – Deshayes, 1825-DescrCoqFoss: 130, 8, pl. 15, fig. 9-10. Deshayes correctly credited this species name to Brongniart. However, Deshayes’ own Paris Basin material was not conspecific with Brongniart’s species, although his figure was of Brongniart’s holotype. Later, Wenz (1924: 222) proposed Bythnella deshayesi for the Paris Basin material, doing so seemingly as a replacement for a junior homonym, but it was a completely new species.
