Clytia hemisphaerica was the most abundant and frequent hydroid species collected. Pedicels of hydrothecae in some colonies are extremely annulated. This is the first record of this species in the Gorringe. Reported distribution . Eastern Atlantic.—Very common (e.g. Russell 1953; Cornelius 1982; Medel & Vervoort 2000), from Iceland (Broch 1918) to South Africa (Millard 1975). Herein reported for the first time in the Gorringe. Mediterranean.—Well dispersed (e.g. Medel & Vervoort 2000; Peña Cantero & García Carrascosa 2002) Elsewhere.—Nearly cosmopolitan through shallow waters, possibly absent from the Antarctic and Arctic, but many old records of the species are dubious (e.g. Ralph 1957; Kramp 1961; Calder 1991; Cornelius 1995 b). The type locality of the species is in Belgium. : Published as part of Moura, Carlos J., 2015, The hydrozoan fauna (Cnidaria: Hydrozoa) from the peaks of the Ormonde and Gettysburg seamounts (Gorringe Bank, NE Atlantic), pp. 148-180 in Zootaxa 3972 (2) on page 168, DOI: 10.11646/zootaxa.3972.2.2, http://zenodo.org/record/237108 : {"references": ["Linnaeus, C.
