discussion
Remarks. Calcigorgia matua mostly resembles C. beringi sp. n. but has very short distinct clubs in the polyps which are lacking in C. beringi. Their distribution overlap in the West Bering Sea, but C. matua also occurs in the Sea of Okhotsk while C. beringi is only recorded from the western Aleutian Islands.
distribution
Distribution. Sea of Okhotsk in 300 (Dautova 2018) — 900 m; West of Bering Sea (western Aleutian Islands) (Figure 1 c).
