Description
Summary:FIGURE 28. Mixtoscutella ussowi (Kluge, 1908). ZIRAS 14/50567 (Korfa Gulf, eastern Kamchatka, Bering Sea). A. Colony margin with developing zooids and ooecia. B. Distal view of two zooids, showing details of orifice and suboral avicularia. C. Orifice of non-ovicellate zooid, showing condyles and suboral avicularium. D. Group of non-ovicellate zooids. E. Zooids with developing ovicells close to colony periphery. F, G. Ovicellate zooids in older part of colony, showing ovicells with ooecia covered by secondary calcification and sutures between secondary calcification arising from distal and distolateral zooids. H. Transverse section through frontal shield, showing interior of proximal margin of orifice, umbonulomorph suboral area with adjacent pseudoporous shield, and cavity of suboral avicularian chamber. I. Interior of frontal shield, showing primary orifice with condyles and elongate suboral umbonuloid component surrounded by pseudoporous lepralioid shield. J. Internal view of primary orifice. K. Basal surface of colony. L. Interior of frontal shield, showing blurred ring scar and umbonuloid component surrounded by pseudoporous lepralioid area. M. Lateral view of zooid, showing frontal shield and lateral wall with mural pore chambers. Scale bars: A, D, G, K, 500 μm; B, E, F, 250 μm; C, H–J, 100 μm; L, 50 μm; M, 200 μm.
