Description
Summary:FIGURE 24. Rhamphostomella echinata n. sp. Holotype, ZIRAS 1/50126 (Medny Island, Commander Islands, Bering Sea). A. Colony margin with developing and fully formed young zooids. B. Lateral view of orifice, showing branching lyrula, four spinules, suboral avicularium and bases of oral spines; non-bleached colony. C. Orifice of non-ovicellate zooid showing lyrula, lateral denticles and bases of oral spines. D. Group of non-ovicellate zooids, showing dimpled frontal shields and early stages of ooecial formation. E. Non-ovicellate zooids with long oral spines; unbleached colony. F. Close-up of non-ovicellate zooid, unbleached. G. Group of zooids with broken and completed ooecia. H. Single ovicellate zooid, showing details of orifice, spine bases and ooecium. I. Interior of frontal shield, showing lyrula, lateral denticles, umbo, ring scar and areolae. J. Basal surface of colony, showing protuberances. K. Interior of frontal shield, showing ring scar and umbonuloid component with lyrula and lateral denticles. L. Lateral view of zooid, showing frontal shield, oral spines and lateral wall with mural pore chambers. Scale bars: A, D, E, G, 250 μm; B, K, 50 μm; C, F, H, I, 100 μm; J, 500 μm; L, 200 μm.
