Campanularia hincksii var. grandis Hirohito, 1983: 15 .

Material examined. Stn. CHL 02 —04.iii.2005, 13– 20 m, S80: a sterile colony epizoic on Symplectoscyphus filiformis ( MHNG INVE 53280).

Type locality. Northumberland, Great Britain .

Description. Small and probably juvenile colony composed of a few hydrothecate pedicels arising singly at irregular intervals from creeping, tortuous stolon. Pedicel slightly undulated throughout or smooth in middle part; with no distinct annuli. Hydrotheca deep campanulate, walls slightly diverging distally to almost parallel; from middle part slightly tapering towards base, most abruptly basally; basal chamber quite high. Subhydrothecal spherule present, between hydrothecal base and pedicel. Hydrothecal rim with ca 8 trapezoidal cusps separated by rounded embayments; cusps with apical, shallow, rounded incision in middle, giving them a bicuspidate appearance. Hydrothecal rim undulated in frontal view; embayments between cusps curved inwardly, cusps curved outwardly. The presence of longitudinal striae on external surface of hydrotheca could not be observed, and this is probably due to fixation. Gonothecae absent.

Remarks. Though sterile, the present material corresponds well with the redescription provided by Ramil & Vervoort (1992), and there is no real doubt concerning its specific identity. An extensive synonymy of this species is available in Medel & Vervoort (2000).

World distribution. Nearly cosmopolitan, except high Arctic and Antarctic waters ( Vervoort 2006).

Records from Chile. This species was found at only one station, Piedra Lile, Isla de Chiloé.
