102 EXPLANATION OF FIGURES IN PLATES. 



Plate VI. — Phyllactinia coryixa. 



Fig. 6o. — Chromatin strands more irregular and passing over into apparent 

 reticulum by formation of anastomoses. 



Fig. 6i. — Still later, chromatin still more irregular and practically in the resting 

 condition. 



Fig. 62. — ^Transverse section of ascus ; nucleus in spirem of second division. 



Fig. 63 a, b. — ^Later prophase of second division ; chromosomes appearing in two 

 sections. 



Fig. 64. — Still later prophase, second division. 



Pig. 65. — Equatorial-plate stage; second division; one spindle lying in plane of 

 section, the other cut through obliquely; eight chromosomes. 



Fig. 66. — Late anaphase stages, second division; eight chromosomes on each 

 half of each spindle. 



Fig. 67 a. — ^Equatorial-plate stages, third division; nuclei in end of ascus; one 

 polar and one side view of the spindle figures. 



Fig. 67 b. — ^Larger nuclear figure from same ascus, which will form functional 

 nuclei ; nuclear membrane still intact. 



Fig. 68. — Anaphase stages of third idivision; eight chromosomes on each spindle- 

 half.
