Boris Sirenko and Mikhail Kokesnikov, 3 August1984; ZIN 11670, same data as ZIN 11665; USNM 1006226, Semisopochnoi Island, Rat Islands, Aleutian Islands, West Bering Sea, 51.8925°N 179.336°E, coll. Slear, J., 21 November 2000. Description . ZIN 11664 is 10 cm high and 5 cm wide (Figure 2b). The stem is 1.5 cm long and about 3 mm wide. Regular lateral branching forms the colony, with branches 2 mm wide. The cylindrical polyps are arranged spirally around the branches, they are about 2–3 mm high and 1 mm wide. Tentacles with scales, up to 0.12 mm long, with a few simple tubercles (Figure 13a). Polyps with small clubs, up to 0.10 mm long, with simple tubercles (Figure 13b). Coenenchyme with capstans, small spindles and cylinders, up to 0.12 mm long, with simple or complex tubercles (Figure 13c). A few crosses are also present (Figure 13d). Distribution . Sea of Okhotsk in 300 (Dautova 2018)— 900 m; West of Bering Sea (western Aleutian Islands) (Figure 1c). 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. : Published as part of Matsumoto, Asako K., Van Ofwegen, Leen P. & Bayer, Frederick M., 2019, A revision of the genus Calcigorgia (Cnidaria, Octocorallia, Acanthogorgiidae) with the description of three new species, pp. 1-27 in Zootaxa 4571 (1) on pages 16-18, DOI: 10.11646/zootaxa.4571.1.1, http://zenodo.org/record/2605876 : {"references": ["Dautova, T.
