FIGURE 4 in Morphology and Molecular Phylogeny of the Soil Ciliate Cyrtohymena seorakensis sp. n. (Ciliophora, Hypotricha, Oxytrichidae)

FIGURE 4. photomicrographs of protargol-impregnated dividing specimens of Cyrtohymena seorakensis sp. n. A. Ventral view of a mid-divider specimen, showing the frontal-ventral-transverse anlagen (arrows) and the undulating membranes anlagen (arrowheads). B. Ventral view of late divider, showing the frontal-ventral-transverse cirri migrate to their original locations. Note the opisthe is the only specimen observed with less number (only 14) of frontal-ventral-transverse cirri in all preparations. C, D. Ventral and dorsal view of very late divider, showing the frontal-ventral-transverse cirri already in their specific locations, and the newly formed caudal cirri (arrowheads) at the end of kineties 1, 2, and 4. CC—caudal cirri; DK1–6—dorsal kineties; DM—dorsomarginal kineties; LMR—left marginal anlage; MA—macronucleus; MI—micronucleus; OP—oral primordium; PTC—pretransverse cirri; RMR—right marginal anlage; TC—transverse cirri. Scale bars: 30 μm.
