 more white; the nape patch, the patch over the shoulder, and the 

 ear coverts and mark on the sides of face are darker and more pro- 

 nounced; and the brown is of a different shade nearer hair brown, 

 while in S. u. ulula it is olive. Below there does not seem to be 

 much difference. There is a specimen in the collection from Pe- 

 tropaulski, Kamtschatka (No. 41010) that does not seem to differ
