Material examined. Stn. COM 02 —22.i.2006, 20– 25 m, S96: one sterile colony, 3.5 cm high. Stn. COM 07 —25.xii. 2004, 22 m, S20: a small, sterile colony, 0.9 cm high, epizoic on Bougainvillia pyramidata (MHNG INVE 53174). Stn.

CCA — 12.iii. 2006, 28 m, S87a: several colonies, about 3–4 cm high, and smaller fragments, one of them with coppinia, epizoic on gorgonian (MHNG INVE 53307). Stn. CFA — 14.iii.2006, 10– 30 m, S88: several fertile colonies and fragments, up to 10.5 cm high. Stn. CVI — 06.iii.2006, S124 (20 m): four sterile fragments, 1.5–2.5 cm high (MHNG INVE 53385); S109 (15–25 m): one sterile colony, 2.7 cm high; S142 (15–25 m): one sterile colony, 6 cm high, on hexacoralian and bivalve shell; S105 (15–25 m): two sterile colonies, both 2.3 cm in height; S86a (15–25 m): one sterile colony, 5.5 cm high (MHNG INVE 53303).
Type locality. Arbroath, Angus, Scotland.
Remarks. The present material agrees perfectly with the description of this species given by Vervoort (1972a). Several fertile colonies were found at Stn. CCA (S87) and Stn. CFA (S88).
Hydroid epibionts. Bougainvillia muscoides (M. Sars, 1846); Bougainvillia pyramidata (Forbes & Goodsir, 1851); Hydractinia pacifica Hartlaub, 1905; Modeeria rotunda (Quoy & Gaimard, 1827); Hebella striata Allman, 1888; Halecium delicatulum Coughtrey, 1876; Sertularella robusta Coughtrey, 1876; Halopteris schucherti Galea, 2006; Clytia linearis (Thornely, 1900).
Distribution. Near-cosmopolitan, being widely distributed in Atlantic, Pacific, and Indian Oceans, penetrating both in Arctic and Antarctic regions (Vervoort & Watson 2003).
Records from Chile. Previously reported from Golfo de Ancud, Strait of Magellan (Leloup 1974), and Trinidad Channel (Hartlaub 1905). The present material was collected roughly between 42°10' S and 52°10' S.
