21a Homomorphic constricted type of chromosome number 3. 



62/ Heteromorphic form of same chromosome from another individual — one 

 homologue constricted the other smooth. 



13a Homomorphic smooth type of same chromosome from a third animal. 



1« The concurrent passage of the atelomitic homologues of chromosomes 

 number 7 and S to the opposite pole from the accessory in specimen number 1. 



lie The same except that the atelomitic dyads are passing to the same pole 

 as the accessory. 



lx The three J-shaped tetrads of animal number one with alternate distri- 

 bution of atelomitic dyads of chromosomes number 7 and 8. 



22/* Homomorphic, atelomitic form of chromosome number 1. 



22c Heteromorphic condition of chromosome number 11.
