Seven tubificid and five enchytraeid oligochaete species are recorded from 63 subtidal sediment samples from the fjords near Bergen. One of the tubificids is considered conspecific to Limnodriloides barnardi Cook, which previously was known from the Pacific coast of Mexico only. A meiobenthic enchytraeid, Marionina sublitoralis sp.n., is described from sublittoral shell sand. It is separated from other, morphologically closely related, species of Marionina by its setal arrangement and its morphology of spermathecae. The other species are Peloscolex benedeni, Peloscolex amplivasatus, Macroseta rarisetis, Adelodrilus sp., Phallodrilus sp. I, (?)Phallodrilus sp. 2, Grania macrochaeta pusilla, G. maricola, G. variochaeta, and G. postclitellochaeta, for some of which taxonomic notes are given. P. amplivasatus and C. macrochaeta pusilla are characteristic of the deeper, finer sediments, while the remaining species are more restricted to the shallower, often shelly sediments. Some other ecological and biological aspects are briefly discussed.
