( fig. 5 F)

Campanularia paulensis Vanhöffen, 1910: 298 , fig. 19.

Material examined. Stn. T10, 15.ii.2007: a few sterile stems, epizoic on plumose bryozoan. Stn. T17, 06.iii.2005: a few sterile stems, epizoic on Plumularia setacea (Linnaeus, 1758) . Stn. T19, 07.iii.2005: a few sterile stems, epizoic on Sertularella gayi (Lamouroux, 1821) .
