FIGURE 12. Rhabdopleura emancipata n. sp., A, B, D, E, paratype NIWA 161566; C, paratype 161211: A, B, distal part of a ringed tube, the bracketed section enlarged in B. C, transmitted-light view of a principal tube (stem) with openings of four ringed tubes all around; tentacles of one young zooid partly emergent; note how black stolon changes position within principal tube; cdc = cone of diaphragm complex. D, close-up of exterior surface of a principal tube showing parallel fusellar annuli marked by thin sutures. E, sclerotized tube, with terminal aperture at left, branching off a principal stolon. Scale bars: A, 200 μm; B, 100 μm; C, 400 μm; D, 100 μm; E, 1 mm.
