Sertularia geniculataLinnaeus, 1758: 812. Obelia geniculata– Cornelius, 1975: 272, figs 1, 5. – Cornelius, 1995b: 301, fig. 70.
Material examined. Stn. T14, 23.ii.2005: several sterile, poorly-preserved stems, up to 10 mmhigh, on Macrocystis pyrifera.
Distribution. Previously collected by the S.Y. Scotiafrom the fronds of Macrocystis pyriferaat Gough Island (Ritchie 1907). This is a near-cosmopolitan species, penetrating high latitudes in the northern hemisphere and into sub-Antarctic waters in the southern hemisphere (Medel & Vervoort 2000).
