Sorry to be a bit absent, I got a grant to work on sponges on Rathlin Island and employ someone on the project so have been concentrating on that. We've recently had a new network installed and as we've no dedicated IT staff I get pulled into that as well!!
I think these photos in Kåre's message [#14460] represent two species - the upper one is Eubranchus doriae in my opinion, certainly an interesting find so far North. The others I'd call Eubranchus vittatus which (as you say) I consider to be a senior synonym of E. cingulatus. E. doriae has rings of bumps on the cerata which are clearly shown in this picture, whilst the cerata of E. vittatus have a series of dark rings but are essentially fusiform, like a thin cigar.

Thanks for the comments. I can see the animal in the upper photo, which I copy alongside, has only the two swellings you mention [message #7187] is characteristic of E. doriae. It looks like she may have two new records from Norway.
