The Bulletin concerns the sedentariate and archiannelid polychaetes of British Columbia and Washington, the northern section of the Oregon Biogeographic Province. A checklist of the 273 species known from landward of the 200-m isobath indicates those species for which we have seen local specimens. Brief instructions for collection, identification, and use of the illustrated keys are given. A tabulated scheme summarizes the principal external diagnostic characters of the families. Keys to all genera from the continental shelves of the cold-temperate North Pacific are provided under the relevant family. The species keys identify the species known from British Columbia and Washington and an additional 19 species, which may be expected there. The diagnostic characters are presented in a series of alternative choices but supplemental characters are added to preclude accidental misidentification of species not yet recorded from British Columbia and Washington but known from elsewhere in the cold-temperate North Pacific. Several new referrals and records are reported. The Bulletin contains about 400 detailed figures. The waters of British Columbia and Washington share 45% of their benthic polychaete species (including errantiate taxa) with the shelf off southern California, i.e., the northern part of the San Diego Biogeographic Province. The commonality is similar to or less than that of the mollusks of the same region. British Columbia and Washington have about 45% of their benthic polychaetes in common with the cold-temperate Northwest Pacific biogeographical provinces as a whole
