. Electron-microscopic structure of protozoa . Text-figure 12. Schematic drawings of sections through a cilium and surrounding structures in Colpidium. Top: transverse section showing continuous outer membrane and alveoli of silverline system. Mucigenic body in secondary meridian at left; secondary meridian at right enlarged above. To right of kineto- some are three sections of kinetodesmal fibrils and row of fibrils composing longitudinal band. To left of cilium are oblique sections of two fibrils of transverse band.

To right of kineto- some are three sections of kinetodesmal fibrils and row of fibrils composing longitudinal band. To left of cilium are oblique sections of two fibrils of transverse band. Lower left: longitudinal section in an idealized plane just barely to right of primary meridian. Postciliary fibrils posterior to kinetosome; kinetodesmal fibril anterior to kinetosome. Lower right: cross-sections through cilium base at successively deeper levels as indicated by lines, a, b, and c on other diagrams. Transverse fibrils to left of (below) cilia in sections a and b. Parasomal sac and fused pellicular ring in section b. Kinetodesmal and postciliary fibril attachments to kinetosome shown in section c. From Pitelka, 1961a. This new picture represents a considerable departure from some, at least, of the classical views of the silverline system inas- much as it is seen to be an arrangement of membranes and not of
