to test this was to mate them to true albmos, and this was 

 accordingly done. 



One of these animals, $1118.1 (Fig-s. 1 and T)), mated 

 to an albino,-^ c?596.3 {PPCCaee), had 4 dnrk-cycd non- 

 extended non-yellow offspring and 2 alhinos. Tlils would 

 make her composition ppCCaee and the eross may be 

 represented as follows:

The other animal, J'li'O^.l (Figs. 8, 4 and 5), was 

 mated to an albino (? 1171.3, Figs. 3 and 4) of the com- 

 position PPCaCae"e. There were 12 offspring. Of these 

 6 were dark-eyed non-yellow tortoises and the other 6 

 were dark-eyed non-extended non-yellows (see litter 151-1-, 

 Fig. 3). This would indicate that 1202.1 was of the 

 composition ppCCee, and the cross would be as follows :
