New reports of benthic species from the french coasts of the eastern English Channel and the North Sea. Twenty six benthic species from several phyla have been found for the first time in the French part of the eastern English Channel and of the North sea : one Nematoda (Synonchus brevisetosus), one Nemertean (Tetrastemma helvolum), twelve polychaeta Annelida (Spio decoratus, Capitella giardi, Mediomastus fragilis, Phyllodoce longipes. Hesionura elongata, Glycera celtica, Glycera oxycephala, Nephtys assimilis, Myriochele oculata. Chone filicaudata. Fabricia sabella and Protodriloides chaetifier), one lamellibranchiata Mollusca (Ensis directus), five Bryozoans (Eurystrotos compacta, Scruparia ambigua, Amphiblestrum flemingii, Hippopodinella lata and Plesiothoa gigerium), one Phoronida (Phoronis muelleri), one Entoprocta (Pedicellina hispida) and four malacostracean Crustacea (Harpinia antennaria, Idotea metallica, Tanaopsis graciloides and Gastrosaccus sanctus). Their biotope and geographical distribution are discussed and compared with data from the literature.
