Description
Summary:FIGURE 7. Spicules of Rossella racovitzae Topsent, 1901. A, mesodiscohexaster of SMF 11877, B, microdiscohexaster of SMF 11878, C, microdiscohexaster of SMF 11729, D, complete ray of calycocome of SMF 11871, E, complete ray of calycocome with microdiscohexaster between its secondary rays from SMF 11895, F, fragmentary calycocome of SMF 11891. Some representatives of rather unusual spicule shapes: G, calycocome of SMF 11736, rays in front and back are missing, H, complete ray of calycocome of SMF 11736, I, microdiscohexaster of SMF 11736, J, mesodiscohexaster of SMF 11889, K, complete ray of calycocome of SMF 11889. Spicules of R. vanhoeffeni armata Schulze & Kirkpatrick, 1910 (ZMH S2932) for comparison: L, microdiscohexaster, scale bar 10 µm, M, complete ray of calycocome, scale bar 10 µm.
