ADDENDUM. 
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 by 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 eges 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 ege 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 Z. nivalis, though the latter often have some small 
streaks. They vary in length from ‘86 to ‘76 inch, and in breadth from 
‘6 to ‘56 inch. The egg figured on Plate 15 is probably that of EF. dwteola, and 
those described by Dresser are probably eggs of FE, pusilla. I intend to 
figure one of these eggs on Plate 68.
