HEREDITY AND ORGANIC SYMMETRY IN ARMADILLO. 



hand, beginning in position 5, is double. The symmetry is 

 that of the mother, but the doubling involves most of the band. 

 The symmetry is a half-band reversal of that in fetus I. in that 

 the doubling begins 5 scutes from the left margin instead of 5 

 scutes from the middle. 



Fetus III. has either no anomaly at all or else has the entire 

 band doubled. It is difficult to decide as to these alternatives. 



Fetus IV. has the anomaly bilaterally symmetrically. One 

 might claim that the anomaly that should have appeared on 

 fetus III. has been transferred to fetus IV. so that the latter has 

 a double dose of it. 



Set C. i, 9 (Fig. 12). 



The mother has in band 3 in the second position from the left 

 a double scute. 



Fetus I. has an extensive doubling beginning 5 scutes from the 



12 



right-hand margin of band I. Thus the symmetry of the mother 

 is reversed. 



Fetus II. has an extensive unequal bilateral doubling beginning 

 after two scutes on the right and three on the left, continuing to 

 the middle on the left and for 13-14 scutes on the right.
