Editor's comment The type species of Bicatillus is not Calyptraea extinctorium as often cited, but the Miocene fossil Calyptraea deformis Lamarck, 1822, by subsequent designation of Herrmannsen (1847). Rehder (1943) recognized this situation and, for Bicatillus of authors, established the new genus Desmaulus. [details]
