FIGURES 8–21. Cinetochilum ovale n in Morphology and infraciliature of a new marine ciliate, Cinetochilum ovale n. sp. (Ciliophora: Oligohymenophorea)

FIGURES 8–21. Cinetochilum ovale n. sp. from live cells (8–12) and after protargol impregnations (13–21). (8–12) Ventral (8, 11, 12) and dorsal (9, 10) views, showing one of the caudal cilia (arrowhead), the contractile vacuole (arrows in 9 and 10), and the oral field (arrows in 12). (13, 16) Dorsal views of the infraciliature, showing the micronucleus (arrowhead) and one of the caudal kinetosome (arrow). (14, 15) Ventral views of the infraciliature, arrow marks the anterior portion of somatic kinety 2, arrowhead indicates the anterior end of SKn-1 with two kinetosomal pairs side by side. (17) Showing the paroral kinety (arrowhead) and the scutica (arrow). (18) To note the anterior-most row in membranelle 1 and the somatic kinety n. (19) Showing the three membranelles (M1–3) and the three postoral kinetofragments (arrow). (20) Focusing on the cyrtos-like structure. (21) A specimen in morphogenesis. Scale bar = 20 µm.
