Actinauge cf. verrillii McMurrich, 1893

Actinauge verrillii McMurrich, 1893: 184; Eash-Loucks, Fautin, 2012: 34.

MATERIAL. PK-37-55, 61.404°N 176.353ºE – 61.397°N 176.328ºE, depth 440– 430 m, sample 23, one specimen collected.

REMARKS. One specimen was collected on the Koryak slope at 430– 440 m. Species of Actinauge have cylindrical column covered by tubercles and resemble the species of the genus Hormathia, but members of Actinauge occur more often on soft bottom, while Hormathia prefers hard substratum. Aboral thickenings on the tentacles are present in Actinauge but not in Hormathia . Actinauge verrillii 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.
