Die Gattung Trilobodrilus (Archiannelida, Polychaeta) von der deutschen Nordseeküste

Abstract

A comparison between T. heideriRemane from the sublittoral zone near the island Helgoland and T. axi nov. spec. from the sandy eulittoral zone of the island Sylt is presented. The two species, having very similar appearance, are separated by the size, the form of the prostomium, the number of segments and the form of the glands in the epidermis. It is most probable that all T. heideri hitherto described for eulittoral habitats are identical with T. axi. © 1967 Biologischen Anstalt Helgoland.
