Material examined. Stn. CAD — 12.iii. 2006, 33 m, S136: small colony with several hydrothecae and gonothecae, on dead gorgonian ( MHNG INVE 53417 ). Stn. CCA — 12.iii. 2006, 28 m, S87k: several hydrothecae, gonothecae rare, on unidentified substrate ( MHNG INVE 53316 ) .

Type locality. Calbuco , Chile .

Description. Colony composed of long, unbranched pedicels springing from a creeping, tortuous hydrorhiza, terminated by a hydrotheca at distal end (total height about 8 mm). Pedicels long, straight, smooth throughout; no annuli or perisarc constrictions. Hydrothecae large, campanulate, broadly rounded basally, lateral walls slightly divergent distally. Hydrothecal margin with 12–16 square-topped cusps, each with a median, small, apical, rounded incision; margin undulated in cross-section, just under rim, undulations being visible on hydrothecal surface as fine, longitudinal striae, running downward. A globular basal chamber is delimited below hydrotheca by a thin diaphragm. Subhydrothecal spherule present. Gonothecae arising from stolon and borne on long, smooth pedicels, with thick perisarc; gonotheca long, fusiform, walls smooth, except distal end provided with fine, transverse striation; aperture small, rounded and terminal.

Remarks. Campanularia laevis Hartlaub, 1905 is a junior homonym of Campanularia laevis Couch, 1844 . Cornelius (1982) introduced the new name Campanularia agas .

Hydroid epibionts. Filellum serratum ( Clarke, 1879) .

World distribution. Antarctica, Brazil ( Leloup 1974), Strait of Magellan ( Vervoort 1972a).

Records form Chile. This species was previously reported from Calbuco ( Hartlaub 1905) and Golfo de Ancud ( Leloup 1974). The present material was collected from both the Canals Adalberto and Castillo.
