FIGURE 9 in Taxonomic studies on three marine species of Frontonia from northern China: F. didieri n. sp., F. multinucleata n. sp. and F. tchibisovae Burkovsky, 1970 (Ciliophora: Peniculida)

FIGURE 9. The population of Frontonia tchibisovae in China after silver carbonate (A, E) and silver nitrate (B – D, F – J) impregnations. (A, F, G) Dorsal views, to show the CVP (arrowheads). (B, C) Buccal area, to show the oral apparatus, arrowheads in B mark the vestibular kineties. (D) Ventral view of a cell ingesting food. (E, J) Pellicle and silverline system structure. (H) Ventral view of a whole cell. (I) To show the paroral membrane (arrow) and the argentophilic line (arrowhead). Scale bars in (A) = 60 µm; in (H) = 80 µm
