Halecium beanii (Johnston, 1838) Halecium beanii : Millard, 1975: 144-145, figs 47A-E; Cornelius, 1995a: 276–278, fig. 62; Ramil et al ., 1998: 7; Medel & Vervoort, 2000: 8–12, fig. 1; Schuchert, 2005: 615–618, fig. 5, 6. Material examined. MSM 16 /3, stn GeoB 14796–1, ROV, 20°14.840’– 20°14.575’N, 17°40.193’– 17°40.071’W, 487–642 m, 3-XI-2010: three colonies 40–60 mm high, attached to Lophelia pertusa , all colonies with female gonothecae. Biology. Halecium beanii has been usually found growing on hard substrata like rocks and concretions and on algae and other invertebrates (Gravili et al . 2015). Fertile material has been found throughout the year (Cornelius 1995a; Gil & Ramil 2017a). Our material was found growing on L. pertusa . Colonies with female gonothecae were recorded in November. Distribution. This species shows a near cosmopolitan distribution in shallow to moderately deep waters, with records in all oceans but the Southern Ocean (Cornelius 1995a; Ramil et al. 1998; Schuchert 2005); its distribution was reviewed in detail by Medel & Vervoort (2000). In West Africa, H. beanii was collected from Morocco (Patriti 1970), Canary Islands (Medel & Vervoort 2000), Cape Verde Islands (Rees & Thursfield 1965), Guinea-Bissau (Vervoort 1959; Gili et al. 1989) and Ghana (Buchanan 1957). Its bathymetric distribution extends from 0 to 1134 m (Millard 1978). Our material was collected from depths of 487 to 642 m. Remarks. The presence of female gonothecae confirms the identification of this material as H. beanii . Its morphology is very similar to that of Halecium halecinum (Linnaeus, 1758), and only the female gonothecae allow accurate separation of both species (Millard 1975; Ramil & Vervoort 1992; Schuchert 2005). : Published as part of Gil, Marta, Ramil, Fran & Agís, José Ansín, 2020, Hydroids (Cnidaria, Hydrozoa) from Mauritanian Coral Mounds, pp. 412-466 in Zootaxa 4878 (3) on page 427, DOI: 10.11646/zootaxa.4878.3.2, http://zenodo.org/record/4425132 : {"references": ["Johnston, G.
