( figure 1J View FIG )
Material examined. ANT IX-3 Stn 176, numerous hydrothecae on Billardia subrufa (RMNH-Coel. 30760).
Description. Stolonal hydrorhiza giving rise, through a short apophysis, to erect and slightly sinuous pedicels supporting a single hydrotheca ( figure 1J View FIG ). Wall of pedicel smooth.
Hydrotheca bell-shaped ( figure 1J View FIG ), ca 853 M m high, resting on a basal spherule ca 64 M m high and 81 M m width, and provided with a distinct diaphragm delimiting a small basal chamber ca 81 M m high. Distinct inflexion point present between basal chamber and remaining hydrotheca. Hydrothecal diameter strongly increasing above basal chamber, only slightly afterwards; minimum diameter at diaphragm (ca 129 M m) and maximum diameter at aperture (ca 483 M m). Hydrothecal aperture circular; rim provided with ca 12 blunt cusps, separated by deep embayments.
Gonothecae not found.
Remarks. Campanularia sp. is close to C. hincksii Alder, 1856 and may even be conspecific. However, the lack of gonothecae in our material prevents us from identifying it with certainty.
Ecology and distribution. Campanularia sp. was found at a depth of 634 m off Fimbul Ice Shelf, Princess Astrid Coast, Weddell Sea. It was found epibiotic on Billardia subrufa .
