Cetoconcha hyalina (Hinds, 1843) (Fig. 3 K, L) Neaera hyalina Hinds, 1843: 76. Cetoconcha hyalina (Hinds, 1843) — Huber 2010: 513. Material examined: four specimens from the sea slope of Iturup, Urup, and Onekotan Islands (123–450 m). Distribution: East China Sea; Sea of Japan; Hokkaido to Shikoku Islands (Japan); Kuril Islands (80–650 m) (Scarlato 1981; Okutani 2000, 2017; Kantor & Sysoev 2005; Liu 2008). Remarks: Previously, only a single specimen of Cetoconcha japonica Habe, 1952, was found at (Iturup Island, depth 300 m) (Scarlato 1981) off the Kuril Islands which was synonymized with Cetoconcha hyalina (Hinds, 1843) (Huber 2010). As our study has shown, the range of this warm-water species extends northward along the Kuril Islands to Onekotan Island.
