Shull, which shows that some of the unit characters of the 

 mutants have a much ^n-eater variabihty than the corresponding 

 features of tlie parent form, and the greater amphtude of the 

 fluctuations is coupled with a decreased correlation. Thus the 

 coefficient of variability of iiaiidla is 3 1.84 ±3.16 per cent., 

 while of Laiiiairkiana it is 5.37 d= 0.44 per cent. The greater 

 variability of the mutants does not, however, seem to result in 

 any diminution of the gap that separates them from the parent 

 form, and no movement in this direction has been observed in the 

 long period which has elapsed since the new species came into 

 existence. A bibliography is added.
