I am not an expert on this fauna but my first thought was that it is Facelina annulicornis. The enlarged scan you have subsequently sent me certainly supports that belief as you can clearly see the two external features which seem to characterise this species - the oblique lamellae on the rhinophores, and the scattered white spots.
I may be quite wrong, but that would be my best guess.
