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.
