The first record of the non-indigenous species Gibbula albida in Finistère coastal waters (west Brittany) is reported. Two specimens together with seven empty shells were found within a muddy-sand-gravel habitat at mid-level of the intertidal area, in the western part of the bay of Morlaix. This is the first record of G. albida in Finistère waters as the species originating from the eastern Mediterranean, has been known from many years to live in the gulf of Morbihan (south Brittany) as well as from north Brittany shores (Bay of Saint-Brieuc).
