(a smaller individual has these three measurements of thickness, respectively, mm., mm., mm.); diameter of nucleus 0,004 mm. to mm., mean mm.; diameter of endospherule mm.; cilia line interval, anterior mm., posterior mm.; basal granules in the lines of the anterior cilia 800 to the millimeter. This species is much like O. raTiaruTn in shape, extept that it is thickest in the middle. Its nuclei run smaller than in 0. ranarumi. Its endospherules are usually small. Its cilia are very numerous anteriorly, the lines of their insertion being close together and the basal granules (cilia) being very close together in these lines. This is a well demarcated species. |. OPALINA LATA Bezzenberger (1904). Host.—Rana limnocharis Wiegmann, from "; I have had no material of this Fig. 213.—Opalina lata, x 350 diameters. (Afteb Bezzbnbesgeb.) Measurernents.—Length of body mm.; width of body mm.; thickness of body mm.; diameter of nuclei mm. The rows of cilia are "extraordinarily close together" and the nuclei are very numerous. This species is ranarum-like in form, but has smaller nuclei. It seems also similar to O. draytonii from western North America and to O. camerunends from western Africa. The rows of cilia are " extraordinarily close together " in the latter species also, and the cilia are very closely set in the rows, so 0. lata and 0. camerunensis agree in being densely ciliated. O. camerun- ensis is nearly twice as thick as O.
