INHERITANCE, FERTILITY, AND SEX IN PIGEONS. 



The Zenaida x Zenaidura hybrid {ZZl) which is used as the sire in table 105 is 

 figured in pi. 20. When this hybrid is compared with the mourning-dove (pi. 19) it 

 is plain that the long tail and the large suborbital spot of the latter have been very 

 perceptibly reduced, and the reddish-brown color increased, in the direction of 

 Zenaida. When this hybrid was mated with a blond ring it will be seen by reference 

 to pi. 20 that once more a fair intermediate results — an intermediate not only in 

 the general coloration, but in the specific parts of the color-pattern. The black 

 spots of the Zenaida and Zenaidura ancestors are again reduced in size and in num- 

 ber toward the uniform color of the ring-dove. The number of tail-feathers (rec- 

 trices) in this fraternity was that of the dam (12) in 4 eases, and that of the sire (14) 

 in a fifth individual.
