Staurotheca antarctica Hartlaub 1904 

( Fig. 3A View Figure )

? Staurotheca antarctica  — Briggs, 1938: 26.

Staurotheca  antarctica— Peña Cantero & Vervoort, 2003: 2670 –2673, fig. 3 (synonymy).

Material examined. 29EV59, a colony 40 mm in diameter, with female gonothecae (IK–2009–0333).

Description. Compact colony 40 mm in diameter, consisting of a mass of stems and branches. Branching frequent and irregular. Branches numerous and provided with anastomoses. Hydrothecae arranged in decussate pairs, forming four longitudinal rows. Hydrotheca ( Fig. 3A View Figure ) small, little immersed into branch. Adcauline hydrothecal wall adnate for about half its length, free adcauline wall curved outwards. Hydrothecal aperture circular; rim with renovations. Female gonothecae on bifid and digitiform process arising from hydrothecal base. Gonotheca  globular, ornamented with digitiform projections.

Remarks. The record by Briggs (1938) was considered doubtful by Peña Cantero et al. (1997) because he gave neither description nor measurements, being unable to confirm the identification. It would be necessary to reeXamine Briggs’s material to clarify its systematic position.

Ecology and distribution. Present material was collected at depths between 452 and 480 m, and with gonothecae in December. Briggs (1938) reported the species at depths between 283 and 720 m from Commonwealth Bay. Circum-Antarctic distribution (Peña Cantero & Vervoort 2003).
