type desci'ibed. They were mated togethei^ late in the breeding- 

 season, having both been previously used to cross with Barb- 

 Fantail F. 1 crosses {v. Exps. 38 & 39). 



Three young only were produced, of Avhich one w^as black and 

 white mottled with the white in excess. Unfortunately no details 

 of the markings of this bird were kept. The other two were black 

 with a few white feathers on the abdomen, and on the rump in 

 one of them. 



Exp, 36. — F. 1 Black mottled with white $ 1 x Black mottled 



with white c? 3. 

 These two birds raised in Exp. 34 were of the second type 

 described. 



Thirteen young were produced : — 



Black 2. 



F. 1 types 8. 



Birds resembling Xun 3. 

 Of the F. 1 types 5 were black with a few white feathers and 3 

 black mottled with white. Two of these, recorded as belonging to 

 the first type, died when about a week old in the nest. The others 

 showed only a few white feathers on the abdomen, rump, and vent, 

 and one had three white flight-feathers and a few other white 

 feathers on the wings. 



In those recorded as mottled the black was distinctly in excess 

 in one case, and in the other two birds the amount of black and 

 white was about equal. The head, " bib," and tail were black in 

 all cases, and several of the flight-feathers were black. Roughly 

 speaking, the back and wing-coverts showed more black feathers 

 than the breast, abdomen, and under parts. In one case (No. 17) 

 the feathers on the back of the neck and the right wing-coverts 

 were black edged with white, giving a " pepper and salt " 

 appearance to those parts. This peculiarity has not been noticed 

 in any other bird. The following are the details of the markings 

 of the three birds whose plumage somewhat resembled that of the 

 Nun pigeon : — 



No. 7. White. Tail black. 2 black flights. A few black 

 feathers on the head. 4 black wing-coverts and one black 

 feather on the breast. The total amount of black was less 

 than in the Nun. 



No. 11. White. Tail black. 7 black flights. A few black 

 feathers on the head. The wing-coverts were slightly 

 mottled, the greatest amount of black being in the 

 scapular region. A few black feathers on the breast and 

 i-ump. 



No. 14. White. Tail black. 8 black flights. A few black 

 feathers on the head and at the carpal joint. In this bird 

 aeain the amount of black is less than in the Nun.
