Collettea cf. cylindrata (G.O. Sars, 1882)

Remarks. A Collettea species recorded under the obsolete name Strongylura cylindrata was reported from four ‘Vitjaz’ stations in the Kurile-Kamchatka Trench, at abyssal and hadal depths, 4895–6710 metres by Kudinova-Pasternak (1970). While not impossible, this record is doubtful since the nominal species is known primarily from West European waters and the NE Atlantic. Another species, Collettea larviformis, from 5000 metres near the Aleutians (Kudinova-Pasternak 1973), is a possible synonymy for the Kurile-Kamchatka species. New material is required for unequivocal identification.
