« This shell, close to Rostellaria Pes Pelecani Lam., can be distinguished from it by its constantly smaller size, its thinner test, but above all by its four fingers, among which the one closer to the spire is almost parallel to it and longer, while it is smaller in Lamarck’s species, and obliquely directed. […] We dedicate this species to the professor Marcel de Serres, who is too famous to need eulogies. » – A. Michaud: “IX— Description de plusieurs espèces de coquilles vivantes de la Méditerranée…”, Bulletin d’histoire naturelle de la société linnéenne de Bordeaux vol. II, Bordeaux 1827.
