Diplodinium cameli f. cameli Dogiel, 1926. (Fig. 1)

Body is ellipsoidal and laterally compressed; prominent operculum; very small caudal lobe on ventral side. Measurements for the organisms in this material identified as D. cameli f. cameli were as follows (mean ± Standard error in m): L= 208.5 ± 3.5 (184­243); W= 140.4 ± 2.5 (119­164); L/W= 1.5 (1.4­1.7). Values are from the measurements of 25 cells. In the original description of this species by Dogiel (1926), he listed the following measurements (in m): L= 195 (160­210); W= 112 (92­130); L/W= 1.7. Morphology of the Diplodinium cameli f. cameli cells in the present study was similar to the description given by Dogiel; however, the cells were slightly longer and considerably wider, resulting in a lower L/W ratio.

Several of the cells identified as Diplodinium cameli in this study possessed lateral spines, which have not been previously reported for this species. Two different forms were observed, one with a single spine on the dorsal side near the posterior end and the other with spines on both sides. These forms are described below:
