Primo & Vazquez 2007: 1796. Stations (events when several trawling operations per station): 2-3- 5-9-12-13 A-17-30(66)-35-42. The largest specimens of the collection reach 20 cm in length. The oral siphon is apical; the atrial siphon opens at 1/4 to 1/3 of the body length (Fig. 12A). Around both siphons the tunic is raised in irregular finger-like papillae. Elsewhere the surface of the tunic is smooth. A trace of red pigment remained on some specimens. A thin vascular web in polygonal meshes can be seen in the transparent surface of the tunic. On the right side the muscular fibres are thin and regularly crossed. On the left side the musculature is limited to the anterior part of the body. The oral tentacles are not numerous: 16 to 20 large ones are distributed in two rings. The dorsal tubercle opens in a U ... : Published as part of Monniot, Françoise, Dettai, Agnès, Eleaume, Marc, Cruaud, Corinne & Ameziane, Nadia, 2011, Antarctic Ascidians (Tunicata) of the French-Australian survey CEAMARC in Terre Adélie, pp. 1-54 in Zootaxa 2817 on pages 20-24, DOI: 10.5281/zenodo.277174 ...
