9 alba X orientalis (17) given 1909. Only one egg; no development = pair 16. 



Pair 17. 



Later a grand-daughter given as mate. This new 9 (OS-D 3-F) was from OS 8-D 3 above and a 9 blond 

 ring, and hatched 1908. 



cFA 1. 4/20/10; same shade of brown as dark hyb. of orient. X risoria dead 5/4/10; 2 weeks. 

 A 2. 4/22/10; no development. 



Pair IS. 

 9 I ris.-J albaXi douraca hyb. (RD 5) given near end of Aug. 1910. 



d"A 1. 9/2/10; color, like risoria; dead 10/10/10. 



9 A 2. 9/4/10; color, darker, more like tur.-risoria hyb.; dead 12/30/10. 3 



1 "This pair of young repeat the two colors of the previous pair, but the first egg here produces light instead of dark 

 color, and the second egg here produces dark instead of light." (F 4) 



3 The data for the bigeneric hybrid OS 8 show it to have been fertile with: 

 (a) the trispecific hybrid D 9 ( = ris.-tur.-alba). 

 (6) the pure St. alba (1). 



(c) the related (grand-daughter) tetrahybrid OS 8-D S-F (= j orient.-^ tur.-^J ris.-J alba). 



(d) the trispecific hybrid RD 5 ( = \ ris.-j alba X j douraca). 



Lighter and darker shades appear, but in most cases the special colors of the several species entering into the cross is 

 noted. 



TABLE 55. 



Pair 19. 



Two of the above offspring (cf OS-A and 9 OS 8-G = brother and sister from OS 8 X a pure alba) were 

 mated 1910, producing the following: 



?A. 5/15/10 ............. 2 OS-A 1 ...... roseate blond ..................... killed 9/10/13 ................ 40+ mo. 



This bird had a large tubercular growth in the region of the right ' gonad, but no gonad discoverable. 

 The only offspring of this brother-sister mating, in which the parents were trispecific hybrids, was therefore 

 an imperfectly soxed individual. 



1 The normal female pigeon has only one gonad the left; the normal male has two. EDITOB.
