♦The X and Y chromosomes of "C'vals are separated pre-reductionally in the 1st division 

 generally, but post-reductionally in the 2nd division in some instances, as occurred in 

 certain species of murine rodents. Further, in some species, they separate in both 

 these ways. For the sake of convenience, notes have been given in the column of remarks. 

 The formula of sex chromosomes without remarks, demotes the usual case where pre-reduc- 

 tion occurs.
