The benthic phyllodocid polychaete fauna of the continental shelf <br /><br />off the Columbia River, northern Oregon, and southern Washington, at depths <br /><br />of 11 to 97 m, is reported. Three species of Eteone and one species of Anaitides <br /><br />are newly described. Eteone (Mysta) barbata is newly reported in the Northeast <br /><br />Pacific Ocean. Ranges are extended for Eteone longa, Anaitides hartmanae and <br /><br />Anaitides longipes, the latter two species new to Oregon and Washington; E. <br /><br />longa is new to Oregon. New records are given for Eteone calif ornica and Eulalia <br /><br />levicornuta. The local distribution, including depths and sediment type(s), of each <br /><br />species is summarized. The distributions of all species in the genus Anaitides <br /><br />overlapped, while those of some species in Eteone were relatively segregated. <br /><br />The occurrence of E. longa following the dumping of dredged sediments from <br /><br />the Columbia River mouth is discussed.
