FIGURE 4. Juxtacribrilina ezoensis n. sp., intertidal, Akkeshi Bay, Japan; A, paratype, NHM 2006.2.27.50; B, paratype, YPM- IZ-106553; C, D, F, paratype, YPM-IZ-106554; E, paratype, YPM-IZ-106555. A. Non-ovicellate zooids in basal layer, showing presence of three or four oral spines and one or two frontal pore chambers on proximal gymnocyst. B. Non-ovicellate zooids in basal layer, showing ubiquitous frontal pore chambers highlighted in white due to electron charging. C. Colony with numerous frontally budded and four marginal (arrowheads) dwarf zooids. D. Dwarf zooids, with three (arrowheads) or four (arrows) costae in frontal shield. E. Dwarf zooid arising from frontal pore chamber. F. Colony margin, showing non-ovicellate zooids in basal layer, and frontal and marginal dwarf zooids. Scale bars: A, D, F, 250 µm; B, 500 µm; C, 1 mm; E, 200 µm.
