280 A CYTOLOGICAL INVESTIGATION OF SOME SPECIES 
normal telophases are entirely absent. In fig. 64 an anaphase is pictu- 
red. Between two groups of chromosomes which move towards the 
poles a group of chromosomes is seen, still lying on the aequator. One 
sees, that the chromosomes of the aequatorial group are just as large 
as those of the groups moving towards the poles. There is consequently 
no question of a longitudinal splitting of these chromosomes. Indica- 
tions of such a splitting can be observed however in some chromosomes 
of each of the three groups. In the middle of the aequator two chromo- 
somes show the geminus-shape. The number of chromosomes is appro- 
ximately 80.

Such anaphases are rather frequently seen. Only in transition-cases 
to this entirely abnormal division one still sees a regular movement of 
the chromosomes towards the poles. 
It is probable that the chromosomes are distributed, purely accor- 
ding to chance, over the daughternuclei. Usually these will obtain ap- 
proximately equal numbers, but it results from the division-figures of 
later stages, that this is not always the case. 
One sees in fig. 65 how the cellwall between the daughter-cells is 
formed. The wall is here still ring-shaped and seems to halve the cell. 
The chromosomes, which are still lying on the aequator, must, accor- 
ding to chance only, get into the one or into the other cell. The number of
