●

affinis , Coralliophaga – Cossmann & Peyrot (1912c: 466-467) listed this Deshayes ms name from a collection label in the École de Mines as being equivalent to the Miocene Coralliophaga deshayesi (Mayer, 1861) [ Cypricardia ].

antiqua , Cypricardia – Sherborn (1922: 17) listed this species, as a Deshayes nomen nudum, from a paper by Boué (1835: 47). It appears there with a footnote only acknowledging Deshayes’ help, so this dangling nomen nudum should be credited exclusively to Boué.
