Bourgetia Terquem & Jourdy, 1869: 51 , 53, ex Deshayes ms. — Type species (M): Melania striata J. de C. Sowerby, 1814 . Incorrectly listed in some references as “Deshayes in Terquem & Jourdy, 1869 ”. Valid genus.

triticea , Melania –Deshayes, 1825-DescrCoqFoss: 107-108, 6, pl. 14, figs 7-8, ex Férussac ms;1832-EncyMeth: 428.1862-DescrCoqFoss: 453. — Type locality: Les Rosières. — Type age: Eocene (Ypresian). This species name was a nomen nudum, also as “ ex Férussac ms” in Defrance (1823b: 471). Bayania triticea (Deshayes, 1825) ( Le Renard & Pacaud 1995: 103, as “Férussac, in Deshayes”). However, this name was first made available in Melania triticea Cuvier & Brongniart, 1822 ( Cuvier & Brongniart 1822: 26), with a minimal description [Très-voisine du Mel[ania] hordacea , mais lisse”] from Epernay, without mention of Férussac, but as ex Defrance ms. Thus, Bayania triticea ( Cuvier & Brongniart, 1822, ex Defrance ms).
