PLATE 14 



Fig. 17. Anaphase; note flagella and other ectoplasmic structures attached 

 to the centroblepharoplasts. X 300. 



rig. 18. Telophase; paradesmose has been absorbed, the spindle fibers and 

 connection of nucleus and centroblepharoplast are lost, but nuclear reorganization 

 has not yet begun. 



Fig. 19. Enlarged nucleus of figure 17. One lagging heterochroniosome may 

 be seen. 



Fig. 20. Telophase of nucleus; spindle fibers still present as well as attach- 

 ment to centroblepharoplast. Heterochroniosome may be found near ends of the 

 other chromosomes. X 1250. 



Fig. 21. Telophase; remains of paradesmose are seen above nuclei; flagella 

 are omitted and the oblique fibers showu with their attachment to the centro- 

 blepharoplasts. 



Fig. 22. Telophase of nucleus. It has rounded up and the chromosomes are 

 losing their parallel position preparatory to forming a network. 



Fig. 23. Telophase: beginning of constriction of the body. Note different 

 relative positions of nuclei. 



Fig. 24. Telophase; nuclear reorganization nearly complete as well as the 

 formation of the new ectoplasmic structures. The alveolar zone, oblique fibers 

 and flagella are shown. 



Fig. 25. A daughter flagellate, after plastmotomy, which here has taken place 

 before the reorganization of the nucleus.
