Abstract
    The present paper deals with a study of desmoscolecids inhabiting the sublittoral fine-sand of Pierre Noire, Bay of Morlaix (France). Two new species are described: Haptotricoma boucheri sp. nov. characterized by 218-227 body rings, each ring provided with a ring of scales and by two large glandular setae dorsally and ventrally on the right body side and three glandular setae dorsally and ventrally on the left body side; Desmoscolex roscoffiensis sp. nov. is distinguished from all known species by the shape of the cephalic setae: fine, long, bearing a flaglike membrane and by its setal pattern, lacking subventral setae on main ring 15. A redescription or additional information are presented on Tricoma islandica Kreis, 1963; T. polydesmus (Southern, 1914) Steiner, 1916; T. steineri de Man, 1922; Desmoscolex deconincki Decraemer, 1975; D. geraerti Decraemer, 1975, and D. longisetosus Timm, 1970.
