FIGURE 6. Juxtacribrilina ezoensis n. sp., subtidal, Akkeshi Bay, Japan. A, E, F, holotype, YPM-IZ-106549; B, paratype, YPM-IZ-106551; C, YPM-IZ-106552; D, paratype, YPM-IZ-106550. A. Portion of colony showing narrow marginal zone of reduced ovicellate zooids in basal layer, including several dwarfs. B. Colony with frontal dwarf zooids crowded in center; ovicellate zooid in primary layer at upper right. C. Frontal dwarf zooids with two, three, or four costae in frontal shield. D. Distal pore chamber of ovicellate zooid in basal layer (in distal view), showing pores in transverse wall (arrowheads) and pore in chamber roof leading to ooecial cavity (arrow); asterisk, ooecium. E. Zooid in basal layer showing developing ooecium; arrow, location of distal pore chamber of maternal zooid (out of view below base of ooecium), from which distal zooid is budding. F. Enlargement from E, showing ooecial cavity, with pore (arrow) at bottom leading to basal pore chamber; asterisk, ectooecium; arrowhead, entooecium. Scale bars: A, B, 500 µm; C, 250 µm; D, E, 50 µm; F, 30 µm.
