P. cornea has commonly been known as Glandina poireti 

 Fer., but that was originally defined solely by a reference to 

 Bruguiere's B. algirus; therefore the name cannot be used 

 for the form which Ferussac figured in his later publication 

 (Hist. nat. Moll.), as Rossmassler, Bourguignat and others 

 have done.
