The term is certainly justified in connection with the remarkable kinetic structures of flagellates belonging to the family Trichonymphidae. In Trichonympha cam- panula, Kofoid and Swezy (1919) describe the system as composed of an external coating of cilia-like motile organs, three zones of. Fig. 63. — Calonympha grassii Foa. (From Doflein.) flagella with their basal bodies, rhizoplasts connecting basal bodies with a great anteriorly placed blepharoplast, and more deeply-lying myonemes which apparently are not connected with the blepharo- plast (Fig. 64). Kofoid and Swezy regard the central organoid as a kind of superblepharoplast, calling it the "centroblepharoplast" since it has the attributes of a centrosome. When it divides the entire aggregate of kinetic elements of the cortical zone divides with it, forming a mitotic figure with centrosomes, central spindle and astral rays (Fig. 54). The connecting fibrils of the centrosomes, unlike.
