One specimen was collected on the Koryak slope at 430– 440 m. Species of <i>Actinauge</i> have cylindrical column covered by tubercles and resemble the species of the genus <i>Hormathia</i>, but members of <i>Actinauge</i> occur more often on soft bottom, while <i>Hormathia</i> prefers hard substratum. Aboral thickenings on the tentacles are present in <i>Actinauge</i> but not in <i>Hormathia</i>. <i>Actinauge verrillii</i> was originally described from the eastern Pacific: Galapagos Islands, the coasts of Chile and California (McMurrich 1893); later it was recorded from the Southwest Pacific (Dunn 1983) and the Northeast Pacific to the Gulf of Alaska at depths 119–4250 m (Eash-Loucks, Fautin, 2012). Our record extends known range of distribution of this species to Northwest Pacific and Bering Sea and is most northern record of this species. However, very wide geographic and bathymetric distribution sometimes may suggest that not all records were identified correctly and more than one species are involved.</p>
