difPerent papers] resemble in coloration the adult birds of the 

 same sex. The young males are green, the young females 

 are red. This has been proved by observations which exclude 

 any doubt as regards their correctness. The frequent occur- 

 rence of green feathers in red, and of red feathers in green 

 immature birds, is not a sign of transitionary plumage, but 

 can only be explained by inheritance from the opposite sex : 

 thus, the green feathers in an immature red (female) bird are 

 inherited from the green father, and vice versa. The general 

 colour of the ancestral Eclectus seems to have been green. 



17. Meyer on Xanthochroism in Parrots. 



~^ [Ueber den Xanthochroismus der Papageien. Von A. B. Meyer. 

 Sitzungsb. Kon. Preuss. Akad. Wissensch. Berlin, 1882, No. 24.] 



Xanthochroism, in our case the anomalous occurrence of 

 feathers with yellow colour instead of their normal colour, 

 has been frequently observed in Fowls. Since we know that 

 " green " is sometimes produced by a yellow pigment being 

 superimposed on a brown to dark pigment. Dr. Meyer 

 is inclined to explain such abnormal yellow feathers by 

 suppression of the underlying dark pigment. Hence xantho- 

 chroism in Parrots seems, to a certain extent, to supplant 

 the albinism of other birds.
