| Summary: | FIGURE 5. Rhamphostomella gigantea Osburn, 1952. A. ZIRAS 3/50129 (western Kamchatka, Sea of Okhotsk). B–J, M. MIMB 3/50213 (Moneron Island, Sea of Japan). K, L. ZIRAS 1/50127 (Avacha Gulf, eastern Kamchatka, Pacific Ocean). A. Colony margin with developing zooids (arrows, communication pores of future ooecia). B. Distal view of young part of colony with non-ovicellate zooids, showing details of the primary orifice and suboral avicularia. C. Lateral view of primary orifice with suboral avicularium. D. Non-ovicellate zooids with suboral avicularia in young part of colony. E. Group of non-ovicellate zooids with suboral and adventitious frontal avicularia in young part of colony. F, G. Ovicellate zooids with adventitious avicularia in older part of colony. H. Lateral view of ovicellate zooids in older part of colony. I. Interior of frontal shield, showing ring scar and areolae. J. Internal view of orifice, showing straight proximal margin and condyles. K. Basal colony surface. L. Frontal shield interior, showing ring scar and exterior wall microstructure of umbonuloid component. M. Lateral view of autozooids, showing suboral and adventitious avicularia, ooecium free of secondary calcification and lateral wall with mural pore chambers.
