Publication date The year of publication is uncertain. The plate "Hélices fossiles" appeared in livraison 25 on 4 August 1832 (Kennard 1942). However, the species was described by Deshayes, who started collaboration with Férussac not before 1839. Deshayes added an entire volume of text (containing the description of this species on p. 395-396) and several captions to the plates. Perhaps he altered the original caption of the plate "Hélices fossiles", which must have been between 1839 and 1851.
