The current authority on Volutidae (in my opinion) is Patrice Bail of France.
He has developed a full classification of taxa that he considers valid.

>Dear all
>In the publication "A taxonomic Introduction to the Recent Volutidae" by P.
>Bail and G.T. Poppe published in 2001, several Volutes were changed from one
>genus to another like Festilyria africana became Calipara africana etc.  It
>does not seem that this has become common practice as the volutes are still
>referred to as before. Without stepping on toes could I please ask to what
>extent this publication is valid? Should one still use the original genus
>or is
>there a move towards the new classification but I am just not aware of it. Any
>help would be appreciated.
