FIGURE 4. F. acuminata from live material (a–c, g) and after silver staining (d–f). Ventral view of a representative specimen (a–e). Prominent characteristic of the anterior spot view of a representative specimen (a) and cytoplasm views of typical individuals (a–d). Ventral and dorsal views of the somatic ciliature and views of the oral ciliature; silver nitrate staining (e, f, i), silver carbonate staining (g, h, j). View of carrot-shaped macronucleus (k).
