Page 142. Since writing the article on the Rustic Bunting, in which I copied the descrip- 

 tion of the supposed eggs of this species given hy Dresser in his ' Birds of 

 Europe/ I have seen three clutches of eggs, said to be of this species, also 

 collected in the neighbourhood of Archangel. As they agree with each other 

 and differ from eggs of any other North-Russian species, it seems probable 

 that they may be genuine eggs of the Rustic Bunting, though this cannot 

 be regarded as proved until properly authenticated eggs have been taken. 

 The ground-colour varies from greenish white to bluish white, and the over- 

 lying spots are greenish brown and the underlying spots greyish brown. The 

 spotting is very profuse and more or less confluent at the large end of the 

 egg; but there are no streaks, the character of the egg being that of a 

 Sparrow rather than that of a Bunting. In this respect they show an 

 affinity with the eggs of Emberiza melanocephala and E. luteola, and, to some 

 extent, with those of E. nivalis, though the latter often have some small 

 streaks. They vary in length from -86 to '76 inch, and in breadth from 

 •6 to -66 inch. The 6gg figured on Plate 15 is probably tha,t of E. luteola, and 

 those described by Dresser are probably eggs of E. pusilla, I intend to 

 figure one of these eggs on Plate 68.
