202 Wager . — The Life-history of Polyphagus Euglenae. 
Fig. 80. Similar stage to Fig. 79, but each nucleus shows granules estimated at about 10-12 
each. 
Fig. 81. Two nuclei in the fusing stage, chromosomes clear. There appeared to be about ten in 
each nucleus, but this was not certain. 
Fig. 82. Single nucleus of sporangium, due to fusion of the two sexual nuclei. 
Fig. 83. Sporangium showing a nucleus in what seems to be a division stage. 
Fig. 84. Division of primary nucleus of sporangium into two. 
Fig. 85. Sporangium showing late stage of two dividing nuclei. The number of chromosomes 
in each daughter nucleus could not be counted, but appeared to be not greater than ten.
