FIGS 34 in Ciliated protozoa from a volcanic crater-lake in Victoria, Australia

FIGS 34±37. Plagiopyla frontata; (34±36) silver carbonate-impregnated organisms showing the oral and somatic infraciliature, and the striated band. The cytoproct opens on the right side of the cell together with two contractile vacuole pores. Cyt, cytoproct; Ma, macronucleus; OA, oral aperture; SB, striated band. Arrowheads in (35) to the stacks of hydrogenosomes in the cytoplasm of P. frontata; (37) cytoplasm of P. frontata with many auto-ūorescing endosymbiotic bacteria. Arrowheads to some of them. Scale bar: 25 mm.
