62 SIBERIA IN EUROPE. CHAP. vi. 



the white cheeks much whiter, and the black hood extending 

 much farther down the back. 



We saw frequent footmarks of hares, and found several 

 snares set by the peasants to catch them. The next day we 

 visited the same ground again. We did not see a single 

 bullfinch, but caught a glimpse of a small spotted woodpecker. 

 We crossed over to the banks of the Zylma, but the birch 

 woods there produced nothing but a solitary marsh tit, which 

 I shot. The woods round Ust-Zylma seemed to be absolutely 

 empty of bird life. Our first eight days had produced only 

 nine species of birds. During the following ten days we 

 increased our list by only three birds the bullfinch, the 

 Siberian jay, and the Siberian marsh tit. 



throughout the whole of Siberia, and 

 which bears the name of camtschat- 

 kensif, has a still greyer back, and the 

 black of the head extends below the 

 back of the head on to the upper back. 

 An intermediate form, however, occurs 

 in Japan, in which the black of the j 



head also extends on to the upper back, 



but in which the colour of the 



upper 



parts is almost as brown as in the 

 British form. In the valley of the 

 Petchora we did not see this species 

 further north than latitude 66.
