Sedentariate and Archiannelid Polychaetes of British Columbia and Washington
註釋This bulletin presents the principal external diagnostic characteristics of the sedentariate & archiannelid polychaetes of British Columbia & Washington in a tabulated scheme. Keys to all the genera from the continental shelves of the cold- temperate North Pacific Ocean are provided under the relevant family. Species keys identify the species known from British Columbia & Washington and an additional 19 species which may be expected to occur there. A checklist of the 273 species known from landward of the 200-metre isobath indicates those species for which the authors have seen local specimens. Diagnostic characters are presented in the specific & generic keys in a series of alternative choices. Supplemental characters from certain species are added to preclude accidental misidentification of species not yet recorded from British Columbia & Washington but known from elsewhere in the cold-temperate North Pacific. Brief instructions for specimen collection, fixation, identification, and use of the key are also provided, along with a glossary & an index to the scientific names.
