36 GEOGRAPHICAL DISTRIBUTION 



whose breeding-range is sujaposed to be confined to the Eastern Palsearctic 

 Region^ from the valley of the Yenesei to the Pacific. Of these two are 

 supposed to be exclusively arctic — 



Tringa acuminata, 

 Charadrius fulvus ; 



two are arctic and subarctic — 



Phylloscopus super ciliosus, 

 Geocichla sibirica ; 



two are only known to breed in a subarctic climate — 



Chatura caudacuta, 

 Geocichla vai'ia ; 



whilst a third is both subtropic and tropic in its breeding-range — 



Turtur orientalis. 



The breeding-range of one species^ an accidental visitor from a subarctic 

 climate, extends from the Pacific to the Ural Mountains — 



Lanius major. 



The breeding-range of one species^ an accidental visitor from a subarctic 

 climate^ extends from the Pacific to the Baltic — 



Carpodacus erythrinus. 



Central Pal^earctic Species. 



The breeding-range of tliirteen accidental visitors may be broadly described 

 as Central Palsearctic^ inasmuch as their breeding-ranges neither extend as 

 far west as the Atlantic nor as far east as the Pacific. Of these the range 

 of eight does not extend west of the Caspian Sea nor as far east as China. 

 One is arctic — 



Bernicla ruficollis; 



three breed in a subarctic climate — 



Anthus r'lchardi, 

 Merula atrig alaris , 

 Syrrhaptes paradoxus ;
