« I received on the part of the Dr. Tiberi, and of Mr. Benoit, from Messina, a small Cytherea uniformly white that seems to show, apart the colour, all the features of Poli’s Cytherea rudis. Messrs Fischer and Crosse were of this opinion, so that I considered it as a simple variant. However, my learned colleague of Portici, [Nicola Tiberi] whose point of view in such matters is far from being worthless, persists in considering this Cytherea as a distinct species, the description of which he is about to give in the Journal de Conchyliologie. I was impressed by this persistence especially since an other conchologist, no less expert, Mr. Mac-Andrew, registered this species as unpublished in one of his catalogs; he found it in Gibraltar and in other places around the Mediterranean. Fostered by these clever collectors’s authoritativeness, I decided to receive in my catalog the present shell, to which Mr. Tiberi gives the name of Cytherea mediterranea. » – M. Petit de la Saussaye: Catalogue des mollusques testacés des mers d’Europe Paris 1869, via BHL.
