Hi Michael,
you mentioned "Polinices heros" now being called "Lunatia heros".
Actually, the correct genus is "Euspira" which has precedence over the genus
"Lunatia" (meaning the name "Euspira" was proposed prior to "Lunatia").
Euspira was introduced by Agassiz in 1838, while Lunatia was established only
in 1847, by Gray. Thus, the correct name for the beast is Euspira heros (Say,
1822), with the brackets indicating that the original generic association
(Natica) has been changed.
Cheers,
Michael Hollmann
