Rossella fibulata Schulze & Kirkpatrick, 1910 (Figs. 2 C, 4, Tab. 3) Synonymy: Rossella fibulata Schulze & Kirkpatrick 1910a: 298 –299; 1910b: 27–29, pl. 7, figs. 2– 2n. Barthel & Tendal 1994: 97–98, fig. 38, pl. 6–8. Material examined. 4 specimens from station 48-1 (SMF 11732, 11905–11907). Other Material examined: ZMH S2931 (original material of Schulze & Kirkpatrick 1910a). Description. Only two of the specimens from SYSTCO I are essentially complete. These are rather small, juvenile ones, which show a habitus somewhat different from that usually described in the literature (see remarks). One specimen (SMF 11906, Fig. 2 C), 5 cm high and 2.5 cm wide, is distinctly barrel-shaped. It has a narrow osculum at the top and a short spicule tuft of anchoring pentactins at the bottom. The surface of the sponge shows a rather rough tissue with some small conules, regularly distributed over the surface. These conules bear thin spicule tufts of mostly one to five spicules. Protruding pentactins are ... : Published as part of Göcke, Christian & Janussen, Dorte, 2013, Hexactinellida of the genus Rossella, of ANT XXIV / 2 (SYSTCO I) Expedition — Antarctic Eastern Weddell Sea, pp. 102-122 in Zootaxa 3692 (1) on pages 110-111, DOI: 10.11646/zootaxa.3692.1.6, http://zenodo.org/record/224084 ...
