First record of the gastropod Fusinus rostratus (Mollusca: Fasciolaridae) on the northern coast of Brittany (Western Channel, France)

The first record of the non-indigenous Fusinus rostratus in northern Brittany (north-west France) is reported. Seven specimens of this predatory gastropod were found on a muddy maerl matrix at about 10 m depth in the inner part of the bay of Morlaix. This is the first record for the Atlantic coast of France as the species originates from the warmer waters of the Mediterranean, Portugal and northern Spain, and was previously unrecorded in the English Channel. Some biometric measures are given.
