Hymenodiscus coronata (Sars, 1872) Reports for the Azores: Brisinga coronata Sars, 1872 — $ Perrier 1896a: 20; $ Koehler 1909: 122–123, 1921a: 2; Brisingella coronata (Sars, 1872) — Mortensen 1927a: 127; Nobre 1938: 28–31, fig. 3; Gage et al. 1983: 285; Downey 1986: 13–15, fig. 6; A.M. Clark & Downey 1992: 468–469, figs. 67b, 70b, pl. 108, fig. F; García-Diez et al. 2005: 48; Hymenodiscus coronata (G.O. Sars, 1872) — Dilman 2006: 183, 2014: 38. Type locality: off Lofoten Island, Norway. See: Downey (1986); A.M. Clark & Downey (1992). Occurrence: Mediterranean Sea and Northeast Atlantic, from Norway and Reykjanes Ridge (Dilman 2006) to off Banc d'Arguin (Mauritania; Perrier 1894) and? Cape Verde (Mortensen 1927a), including the Azores and Canaries (Koehler 1909). Depth: 100– 2,904 m (Tortonese 1965); AZO: 919– 2,870 m (Perrier 1894, Koehler 1921a). Habitat: soft bottoms, sand, mud to Globigerina ooze (Koehler 1909); a suspension feeder (copepods) and a predator (Howell et al. 2003). Larval stage: lecithotrophic (McEdward & Miner 2001). Remarks: from the Azores, Hymenodiscus coronata is only known from the historical reports by Perrier (1896a) and Koehler (1909, 1921a) based on material collected by Talisman and Princesse Alice at several stations. The southern-most record of this of species appears to be located off Banc d'Arguin, and not in Cape Verde as reported by the related literature (e.g., Mortensen 1927 a, Grieg 1932, Downey 1986, A.M. Clark & Downey 1992, Dilman 2014). The Talisman reports published the station locations using a French coordinate system (Paris Meridian). Later authors may not have been aware of this and might have placed Perrier (1894) ’s record near the archipelago waters, instead of the continental NW African waters (sta 96, 1883: 19°19'00"N, 18°01'46"W).
