^' This is a race, which has a well developed horny endosperm. 

 The number of geimini in the hetero type division was not 

 determined, but it is, believed to be 10, since it was ascertain- 

 ed that this race had 10 chromosomes (Figs, 27, 28, 29, 30, 

 32, 33) in the interkinesis and in the metaphase as well as 

 telophase of the homotype division. 



' Sugar Corn.' 



This race has wrinkled more or less translucent white kern- 

 els. The number of gemini of this race is always 12 (Figs. 20, 

 21). The difference of size and shape of chromosomes in the 

 metaphase of the heterotype division is not so remarkable as 

 in the red starch corn above described ; but certain difference 

 in size and two sets of the same forms among them can be 

 well recognized. 



'Early Eight Sugar Corn.' 



This is a sugar corn whose kernels are of light amber 

 color. The number of gemini is usuallj^ 12 (Figs. 6, 22) as in 

 ' Sugar corn,' but, though very seldom, there are some 

 fluctuations of number ; a case of 9 gemini was found (Fig. 23). 

 A comparison of both figures does not show any remarkable 

 difference of size and shape of gemini. Once I have met with 

 the case where one of gemini separates into the univalent 

 chromosomes already at the diakinesis stage (Fig. 6). 1 have 

 also noticed sign of such separation in the A^ellow starch corn 

 of Tsuyama. 



Red Sugar Corn. 



I got this race in the botanical gardens of our college. As 

 both races of sugar corn above stated have had 12 gemini 

 instead of 10 which were usual among starch corns, 1 expected 

 that this race also had 12 2:emini. But the fact turned out to
