Moura, Carlos J., 2015, The hydrozoan fauna (Cnidaria: Hydrozoa) from the peaks of the Ormonde and Gettysburg seamounts (Gorringe Bank, NE Atlantic), Zootaxa 3972 (2), pp. 148-180 : 151

Bougainvilliidae indet.

(fig. 2B)

Material studied. Gettysburg, stn 7: abundant, creeping on algae and Eudendrium armatum , DBUA 1505.01.

Remarks. Maximum shoot size is 1200 µm; undetermined nematocysts: 7x 3 µm; perisarc tube usually annulated basally, occasionally distally, usually straight; pseudohydrotheca present, one whorl of filiform tentacles, hypostome salient and rounded-conical. The morphology is similar to that of Rhizorhagium roseum Sars, 1874 . The absence of specimens with gonophores prevents an accurate identification. This is the first record of a Bougainvilliidae taxon in the Gorringe.
