 base of the membrane, axostyle, food-lnclusion;T {rac), luicleus, basal body, 

 and the widely open cytostome. 



Fig. — 7. Stages of encystment of T. inacrostoma. 



Fig. S— 12. G ignntomonas herculea. 



Fig. 8. Amoeboid form of Giijaniomonas: inside it is food and the 

 a.xostyle {nx). 



Fig. 9. Gigantomonas viewed dorsally. At the anterior end 2 flagella 

 are seen, the cytostome-mavi^in, nucleus and externally to it the karyosome 

 (c); the other karyosome lies at the posterior end of the body. Inside tlip 

 body a large chromidiuni and fine chromidial rods are seen. 



Fig. 10. Gigantomonas from the left side (the drawing of the membrane 

 has failed), />— cytostome-margin. 



Fig. 11 and 12. Nucleus of Gigantoinonas .'ukI tin- formation of the 

 karyosome externally to it. 



Fig. 13—1.5. Mj/xomonas potipnorpha. 



Fig. 13. The anterior end of a specimen of type A. A dark nucleus with 

 the spirem is seen, the commencement of the axostyle (aa?), the commen- 

 cement of the undulating membrane and two basal bodies with flagella 

 {ft:). 



Fig. U. The nucleus, membrane and axostyle removed from the body 

 of Mfixomonns. 



Fig. Id. idem. The border-filament of the membrane has torn off from 

 the latter in a small portion. 



TABLE II. 



All the drawings except fig. 21 were made with the magnification: compens. 



ocul. 6; obj. immersion of Zeiss 2 mm. 



All the drawings represent Mjixotnonas. 



Fig. 16. Type A. The nucleus with axostyle and membrane removed 

 from the body of the animal. 



Fig. 17. Type .4. The ectoplasm and endoplasm in the given specimen 

 are badly differentiated. 



Fig. 18. Type A. The granulated endoplasm with large vacuoles and 

 the homogeneous ectoplasm are well seen; at one end of the body there 

 are ectoplasmatic papillae {x). 



Fig. 19. Typo B, without axostyle. 



Fig. 20. Type C; one of the few specimens containing food in the en- 

 doplasm.
