I have some difficulties in identifying this nudibranch. BUt on lookinh through your site I think it is Calmella cavolini Verany, 1846. I guess you will confirm this in your answer... Many thanks and congratulation for this site which is admirable.

Thanks very much for these nice photos. From the colour and general shape of the animal I am pretty sure it is Calmella cavolini. The purple marks on each side of the head are very characteristic and are the internal jaw plates, which are purple in this species, showing through the almost transparent body wall. Another distinctive feature, which you can't see that clearly in these photos, is that each group of cerata has a common stalk or lobe on which all the cerata are attached.
