Material examined . Stn. MEL 02 —06.iii. 2005, 15 m, S81: sterile colonies, epizoic on Symplectoscyphus filiformis , with some hydrothecae arising from hydrothecae of the host; S78: a sterile colony, epizoic on Symplectoscyphus subdichotomus (MHNG INVE 53276). Stn. MEL 03 —08.iii.2005, 20– 30 m, S90: a colony with rare hydrothecae, epizoic on Symplectoscyphus filiformis . Stn. CFA — 14.iii.2006, 10– 30 m, S88: a sterile colony, epizoic on Sertularella polyzonias (MHNG INVE 53323). Stn. CPA — 09.iii. 2005, 15 m, S170: several hydrothecae, without gonothecae, epizoic on Symplectoscyphus subdichotomus . Stn. GDA — 07.iii. 2006, 11 m, S115: several hydrothecae, without gonothecae, epizoic on Grammaria abietina (MHNG INVE 53369). Stn. CVI — 06.iii.2006, 15– 25 m, S142: several sterile colonies, epizoic on Symplectoscyphus subdichotomus and Lafoea dumosa . Type locality . Puerto Hambre (Port Famine), Strait of Magellan. Remarks . For a description of this species see Vervoort (1972a). All the present material is sterile. The hydrothecae have numerous transverse striae on their entire length, although Vervoort (1972a) reported a variable degree of striation, usually with the apical fourth of the hydrothecal wall smooth. Gonothecae of H. striata have been described by Hartlaub (1905), who also reported the presence of medusa buds. This species may occasionally have a parasitic habit: El Beshbeeshy (1991) figured hydrothecae of H. striata arising from the hydrothecal openings of Symplectoscyphus sp. A similar situation was observed here in sample S81, where the species occured on S. filiformis . World distribution . Hebella striata is both a sub-Antarctic and Antarctic species, and was recorded from Tierra del Fuego, Falkland Islands, Strait of Magellan, Peninsula Valdés, Kerguelen and Crozet Islands and Antarctica (Vervoort 1972 a, Millard 1977). Records from Chile . This species was previously reported from Golfo de Ancud, Canal Calbuco (Leloup 1974), Smythe’s Channel, Long Island and Puerto Hambre (Hartlaub 1905). The present records extend roughly from 43°50' S to 52°10' S. : Published as part of Galea, Horia R., 2007, Hydroids and hydromedusae (Cnidaria: Hydrozoa) from the fjords region of southern Chile, pp. 1-116 in Zootaxa 1597 (1) on pages 51-52, DOI: 10.11646/zootaxa.1650.1.4, http://zenodo.org/record/5097970 : {"references": ["Allman, G.
