. Bulletin - United States National Museum. Science. THE OPAUNID CILIATE INFUSORIANS. 109 This material is poorly preserved and the intranuclear phenomena are not well seen. The form of the body is sufficiently well indicated in the figures. In most individuals, even in some of the broadest ones, there is a posterior point with rounded tip. In the ordinary individuals we find two nuclei, each more or less elongated ellip- soidal. In the daughter cells we see one similar nucleus, or a single more elongated spindle-shaped nucleus, or two nearly spherical daughter nuclei not connected by a thread


. Bulletin - United States National Museum. Science. THE OPAUNID CILIATE INFUSORIANS. 109 This material is poorly preserved and the intranuclear phenomena are not well seen. The form of the body is sufficiently well indicated in the figures. In most individuals, even in some of the broadest ones, there is a posterior point with rounded tip. In the ordinary individuals we find two nuclei, each more or less elongated ellip- soidal. In the daughter cells we see one similar nucleus, or a single more elongated spindle-shaped nucleus, or two nearly spherical daughter nuclei not connected by a thread. It seems then that. Fig. 75.—Zelleriella cusconiSj x 460 diameters : a, an individual almost ready FOR fission; b and e, cells of the usual sort; c and d, daughter cells; /, an optical, longitudinal section of the body through one nucleus, showing thb thickness of thb body. fission is consummated while the nuclei are ellipsoidal, nearly twice as long as broad. In body form Zelleriella cusconis resembles Z. dendrohatidis and Z. [houlenfferi], but its resting nuclei in ordinary individuals are ellipsoidal and not spherical as in the latter two species.
