Unknown murexes

[Emma]

The way I understand Poseidon, he is saying that the Hexaplex cichoreum was named by Gmelin in 1791 and that the same shell was "renamed" Hexaplex endivia by Lamarck in 1818. I think the discussion is purely taxonomical. In a nut shell, it's the same shell with two different names, named by two different people. I know it as Hexaplex cichoreum and I have also bought them as Hexaplex cichoreum. However, the other name appears to be a synonim. I have been collecting for over 20 years and I have only read the 'endive' name as the non-scientific name, so I'm all out of ideas, I'm affraid. I wish I could be of more help to you, my friend!

Best wishes, Emma.
