  • Venilia mucronifera Alder & Hancock, 1844
  • Zephyrina pilosa de Quatrefages, 1844




Eminently an Atlantic and extremely rare species, it has only been reported from Malahide Bay, Ireland (Alder & Hancock, 1844), in Clyde Bay (Thompson & Brown, 1984), in Loch Torridon, Scotland (top photo), in Vikaneset, Kristiansund, Norway (Christian Skauge, 2007 in Sea Slug Forum) and on the French Atlantic coast in Saint Vaast la Hougue (Quatrefages, 1844) and Roscoff (Vayssière, 1913). The report of Fez (1974) in the coasts of Finisterre (Galicia, Spain) is most probably a confusion since it alludes to a report by Vayssière in Roscoff (Finistère, France).
