EXPLANATION OF PLATE III. 
All figures drawn to scale, using Zeiss’ achromatic objective 1/12" or apoehromatic 
2 mm. homog. immersion, with compensating oculars 8 and 12. 
Figm-es 1—12 stained with iron-haematoxylin. Figs. 13 and 14 with Delafield’s 
haematoxylin. 
I. Embadomonas agilis, nov. gen. et nov. sp. 
Fig. 1. Individual viewed from front, showing eytostome. 
Fig. 2. Large individual from same aspect, but with sides of eytostome projecting in 
lip-like manner. 
Fig. 3. Embadomonas in side-view, to show slipper-like form. 
II. Crithidia eampaniilata, L^ger. 
Fig. 4. Slender flagellate individual showing narrow undulating membrane, long

Fig. 5. Plump flagellate with well-marked undulating membrane. 
Fig. 6. Shortening of flagellum and broadening out of anterior end to form attaching 
surface of encysting stages. 
Fig. 7. Early stage of rounding up. 
Fig. 8. Encysting form in which the cytoplasm is full of darkly-staining granules. 
Figs. 9—12. Campanulate encysting stages. In flg. 10 the nuclei are dividing.
