Abstract
<jats:p>The pellicular framework of Opalina obtrigonoidea consists of numerous longitudinal ribs parallel to the kineties. These ribs lie erect on the cell surface, and each is composed of striated longitudinal fibers. A membrane covers the ribs and the ectoplasm between them. Flagella, of conventional structure, emerge from the ectoplasm between the ribs. The two central fibers of each flagellum end at the cell surface; the nine peripheral fibers continue for about 400 mµ into the cell to form an open tubular kinetosome. From the anterolateral curvature of each kinetosome arise two rows of fibrils, each fibril oriented perpendicular to the cell surface and abou...
