The errantiate polychaetes from waters deeper than 200 m in Hardangerfjorden include 37 species of which 5 are newly described. These include
Nothria fiordica,
Eunice dubitatus,
Lumbrineris agostos,
L. aniara, and
L. scopa. The faunal composition indicates a close relationship to shallow water faunas in the region, and differs from the usual composition of deep-water polychaetes. A preliminary analysis indicates the presence of ecological groupings of polychaetes in Hardangerfjorden.
