Material. 1 specimen from station 048-1 (SMF 11810), 602.1 m , 70° 23.94' S , 8° 19.14' W , 12.01.2008 . Description. Sponge massive, surface hispid with few oscules about 5 mm in diameter. Skeleton of very long primary paucispicular fibres, oriented towards surface, interconnected irregularly by single spicules. Ectosome a palisade-like arrangement of oxeas based on main fibres. Oxeas 490–550 µm x 15 µm, sigmas about 35 µm. Remarks. The species has been well characterized before by Kirkpatrick (1908), Burton (1932, as H. rudis ) and Desqueyroux-Faúndez and Valentine (2002). Our specimen is in general accordance with the species description by Kirkpatrick (1908). The species and its reassignment to the newly created genus Hemigellius by Burton (1932) are of a complicated taxonomic history which is analyzed in Desqueyroux-Faúndez and Valentine (2002).
