Dear Bill,

I think Peter van Bragt is correct. The specimen in the photo seems to be Archidoris pseudoargus Rapp, 1827. The problem is that the picture is a little blurry and a positive identification is difficult. I forgot that I had a picture of Archidoris pseudoargus that looks like the specimen from France. You might want to include if for comparison. The photo is not that great, but the specimen has been properly identified, with anatomical studies.

Regarding the name of this species, I believe the oldest available name for it is Archidoris pseudoargus. The drawings in the original description of Doris tuberculata (Müller, 1778) clearly represent a phaneobranch dorid, probably a species of Adalaria or Onchidoris. The identity of Doris tuberculata has not been determined yet, but it is definitely a different species. Most authors who used the name tuberculata for Archidoris pseudoargus followed Cuvier's (1804) paper. He was the first person to use the name Doris tuberculata for specimens of Archidoris pseudoargus.

Literature cited:
• Müller, O.F. (1778) Molluscorum marinorum Norvagiae, Decas 1. Nova Acta Physico-Medica Academiae Cesariae Leopoldino-Carolinae 6: 48-54.
• Cuvier G. L. (1804) Mémoire sur le genre Doris. Annales du Muséum National d'Histoire Naturelle 4: 447-473, pls 73-74.

Dear Angel,
Thanks for the confirmation and the photo. And sorry about the name change Peter. I am afraid these things aren't really voluntary. Every now and then we have to sacrifice a favourite name for the sake of stability. I remember years ago being very concerned with having to change the name of the chromodorid genus Casella to the much older Glossodoris. Today most workers wouldn't know what I was talking about if I used the name Casella.

Best wishes,
Bill Rudman.
