FIGURE 4. A and B: Clytia linearis (Thornely, 1900) — fragment of colony (A); gonotheca (B). C: Clytia macrotheca (Perkins, 1908) — hydrotheca with pedicel. D: Cirrholovenia cf. tetranema Kramp, 1959 — fragment of colony, with hydrotheca (left) and nematotheca (right). E to G: Halecium cf. lankesteri (Bourne, 1890) — fragments of colonies (E); two stems with male gonothecae (F); nematocysts (G).
