Description
Summary:FIGURE 7. Rhamphostomella morozovi n. sp. Holotype, ZIRAS 1/50570 (western Kamchatka, Sea of Okhotsk). A. Growing margin of bilaminate colony, showing only one layer of developing zooids. B. Lateral view of zooids in young part of colony. C. Zooidal orifice with suboral avicularium (communication pore of future ooecium visible near distal margin of orifice). D. Group of non-ovicellate zooids in young part of colony (arrows, communication pores of future ooecia). E. Zooids with developing ooecia. F. Zooids with developing and nearly completed ooecia and small adventitious avicularia. G. Zooids with developing and nearly complete ooecia and small (central to proximal) adventitious avicularia. H. Lateral view of ovicellate zooid, showing ooecium embedded into secondary calcification and having slit-like proximal pseudopores; notice nearly identical size of suboral and adventitious avicularia. I. Interior of frontal shield showing ring-scar, areolae and communication pores of adventitious avicularium. J. Internal view of orifice, showing straight proximal margin and strongly reduced, pointed condyles. K. Basal surface of encrusting part of colony (some zooids damaged). L. Close-up of frontal shield interior, showing ring scar and exterior wall microstructure of umbonuloid component. M. Lateral walls of zooids in bilaminate colony, showing mural pore chambers. Scale bars: A, D, G, K, 500 μm; B, E, F, H, 250 μm; C, I, J, 100 μm; L, 50 μm; M, 200 μm.
