Flabellina verrucosa from Ireland is F. browni

From: Bernard Picton

Hi Bill,
No, the photo is Coryphella browni, ceratal arrangement is subtly different and the white bands on the cerata are broader. Coryphella verrucosa has a restricted distribution in Ireland, only found on the Irish Sea coastline and the North Coast, entirely within Northern Ireland and not in the Republic. There is a zoogeographic boundary in this region, roughly Malin Head on th North Coast and the entrance to the Irish Sea at the south. C. verrucosa does occur on the Isle of Man.

Thanks Bernard,
Some of these aren't so easy from single photos. I wondered about Flabellina browni but don't know your fauna well enough to see the subtleties.
Best wishes,
Bill Rudman
