Abstract: By brief extraction and fixation in Triton X-100 PIPES fluid contaning glutaraldeyde (2.5%), intact fibrllar framework in the cell of O.danica was revealed. The fibriller framework consists of. (1) An inverted Y shaped microtubular trunk fiber at the anterior end, with its axis running anteriorly and dorsally, and its 2 armsrunning along the sides of kinetosomes ventrally and posteriorly, longitudinal fibrils of various thickness running from the trunk fiber posteriorly, some of which dividing repeatedly, resulting in isolated microtubules to the tail of the cell. (2)A pair of thin fibril arisingnear the base of the short flagellum, and running ventrally and forming loops around the basal part of the short flagellum. (3)A striated ribbon like or triangular rhizoplast originating from thekinetosome of the long flagellum and ending with its broad to the nuclear membrance. Treating extraced cells with colchicine (10ml)or with (NH₄)₂SO₄ 250mmM resulted in disappearance of all the fibrils except rhizoplast and flagella.
