"Examination of the types in the Zoological Museum, Uppsala University, Sweden, showed them to belong to a pulmonate species, presumably Cochlicella barbara (Linné, 1758). (...) The name has also been considered a synonym of Lymnaea glabra (Müller, 1774), Hydrobia ulvae (Pennant, 1777), Hydrobia ventrosa (Montagu, 1803) and Caecilioides acicula (Müller, 1774)."
