EXPLANATION OP PLATES 



All figures are made with camera lucida from smears fixed in hot Schaudinn's 

 fluid and stained with iron-haematoxvlin. X 2500. 



Conncilmania mvris 



Fig. 1. Motile amoeba, showing hyaline pseudopodia. Undigested food is 

 in some of the vacuoles. The large, dark-staining mass in the vacuole to the 

 right of the nucleus is probably Sphaerita. 



Fig. 2. Attached motile amoebae forming balloon like hyaline pseudopodia. 



Fig. 3. Amoeba with typical hyaline pseudopodium formed as if in progressive 

 movement. Note the posterior, root-like projection. The nucleus sliows the 

 thin membrane and diffuse karyosome, characteristic of this species. 



Fig. 4. Rounded, motile amoeba, with partly digested Chilomastix in the 

 large food vacuole. 



Fig. 5. Rounded, precystic amoeba. Note the absence of food in the vaciioles 

 and a small number of large vacuoles, indicating that smaller ones have 

 coalesced to fonn the large ones. 



Fig. (i. Rounded, pre-cy.stic amoeba with tliree large vacuoles. Karyosome 

 is composed of diffuse granules and has a gray area in center. Note the short 

 intradesmose. 



Fig. 7. Mononucleate cyst with large glycogen vacuole and nucleus in 

 early prophase. Small chromatoidal bodies around the margin of the vacuole.
