Intracellular patterns of oxidation and reduction in Chlamydodon pedarius KANEDA were observed by using various indicators (Janus green B, Nile blue sulfate, Methylene blue and Thionin). 1. In many species of Chlamidodon, two opposed gradients are traced. They decrease from both anterior and posterior end to the center of the organism, and unequal in extent. Indicator oxidation decreasing from the cross striped band to dorsal surface is traced only at the anterior region. 2. It is a noteworthy fact that in this ciliate the polarity of the macronuclear component is in accord with the direction of the longitudinal gradient patterns. 3. It is probable that the presence of gradient patterns can be ascribed to the defference of redox potential in the different regions of the cytoplasm, and moreover, to the dorso-vental and antero-posterior diffenrences in some properties. 4. In the Chlamydodon, the appearance of redox patterns is distinctly to be more rapid in the ventral side than in the dorsal, at the anterior part than at the posterior in the ventral portion, and at the pharyngeal basket and the cross-striped band than in the surrounding cytoplasm. 5. From the observations on Chlamydodon and the other ciliates, the writer knows surely that the region showing the higher cellular differentation is more rapid than the other cytoplasmic portion in the reaction of oxido-reduction.
