Figure 16. Parasmittina soulesi Scholz and Cusi, NSMT-Te 1097: (a) marginal autozooids, showing alyrulate orifice (bottom centre) and orifice with weakly developed lyrula (right); (b) orifice with welldeveloped lyrula; (c) ovicelled autozooids; (d) periancestrular zooids (one distal, two distolateral, and two proximolateral; ancestrula obscured, but very broad lyrula evident. All panels are scanning electron microscopic images of bleached specimen. Scale bars: a = 300 µm; b = 100 µm; c, d = 250 µm.
