Bathydorus spinosus Schulze, 1886 (Fig. 8) Material examined: all ANDEEP III, SMF 10526, SMF 10526a, & SMF 10526b, SMF 10707, R.V. 'Polarstern', stn PS67/102-11, Weddell Sea, Antarctica, 0 6 Mar. 2005, 65º35.40'–35.51'S, 36°29.00'–28.83'W, 4794–4797 m, ethanol. Description and remarks: Three specimens and fragments obtained from a single station all correspond well with the original description of Bathydorus spinosus. The best specimen is a thin walled funnel 88 mm tall, 145 mm wide when flattened, with a distinct marginal fringe of large diactins projecting 8 mm (Fig. 8). Spiculation of all specimens conforms to the simple pattern known for the species, with oxyhexasters as the only microscleres. It has been collected earlier from the Weddell Sea as reported by Janussen et al. (2004), and its wider Antarctic distribution has been reported by Barthel and Tendal (1994). FIGURE 8.
