Recently, an overview (Severijns, 2002) of the distribution of Ensis directus (Conrad, 1843) in Europe since its introduction near Hamburg in 1978 (von Cose1 et al., 1982) till the year 2000 was given. The southern most location where the species was found up to 2000 was Merville-Franceville-Plage, on the east bank of the mouth of the river Ome, near Caen (Fig. 1 ). In this paper new observations on the distribution of E. directus in France, which were carried out over the last three years, are presented and discussed. It follows that E. directus has now reached the region of St. Vaast-La-Hougue.
