Caulophacus (Oxydiscus) weddelli Janussen, Tabachnick & Tendal, 2004  

( Fig. 9 View FIGURE 9 )

Material examined: SMF 10527 View Materials , ANDEEP III Exped., R.V. 'Polarstern', stn PS 67 /094- 11, Weddell Sea, Antarctica   , 0 2 Mar. 2005, 66° 38.05 'S, 27 °05.90'W to 66 ° 38.10 'S, 27 °05.46'W, 4893–4894 m, ethanol.

Description and remarks: The second known specimen of this species is nearly complete in its upper part, but is lacking most of the stalk ( Fig. 9 View FIGURE 9 A). It is a stalked funnel, similar in form to the type specimen collected in 2002 on the ANDEEP II Expedition ( Janussen et al., 2004), but much larger, 201 x 136 mm. Spiculation is identical to that of the type material, with the same dermal pinule ( Fig. 9 View FIGURE 9 B), but with addition of a few onychohexaster microscleres ( Fig. 9 View FIGURE 9 C). The new collection location is 446 km southwest of the type location at a similar depth.
