A total of 15 genera and species distributed in 10 families of Polychaeta is reported from hydrothermal vent sites on the Juan de Fuca and Explorer ridges off British Columbia and Washington. One genus and 10 species are new to science. New taxa include Protomystides verenae (Phyllodocidae), Nereis piscesae (Nereididae), Hesiodeira glabra and Amphiduros axialensis (Hesionidae), Sphaerosyllis ridgensis (Syllidae), Ophryotrocha globopalpata and Parougia wolfi (Dorvilleidae), Orbiniella hobsonae and Leitoscoloplos pachybranchiatus (Orbiniidae), and Nicomache venticola (Maldanidae). The hesionid Hesiospina vestimentifera and the ampharetid Amphisamytha galapagensis, previously reported from other eastern Pacific vent sites, are newly recorded. The scalibregmatid Axiokebuita millsi, previously known from deep-sea locations in the North Atlantic and Antarctic, is new to the northeastern Pacific. Additional records of the recently described alvinellid, Paralvinella pandorae, are reported.
