Summary:FIGURE 9. Rhamphostomella aleutica n. sp. Holotype, NHMUK 2010.4.21.1 (Amchitka Island, Aleutian Islands, Bering Sea). A. Colony margin with young, fully formed and developing autozooids (arrow, developing ooecium). B. Orifice with suboral avicularium. C. Suboral avicularium. D, E. Non-ovicellate zooids in young parts of colony, showing inflated cystids of suboral avicularia. F. Group of non-ovicellate and ovicellate zooids, showing traces of repair after damage. G. Close-up of autozooids in older part of colony, showing details of secondary orifice, suboral avicularia and ovicell. H. Frontal view of ovicellate zooid. I. Interior of frontal shield with ring scar and areolae. J. Basal colony surface. K. Close-up of frontal shield interior, showing ring scar and exterior wall microstructure of umbonuloid component. L. Lateral view of zooid, showing ooecium with peristome and suboral avicularium as well as lateral wall with mural pore chambers. Scale bars: A, J, 500 μm; B, C, I, 100 μm; D–F, 250 μm; G, H, L, 200 μm; K, 50 μm.
