Finmark across Siberia to Alaska, and passes in great numbers on 

 migration along the coasts of China and Formosa, to winter in the 

 islands of the Malay Archipelago, the Burma peninsula, and the 

 South Andaman Islands. 



36. PHYLLOSCOPUS XANTHODEYAS. 



(SWINHOE'S WILLOW-WARBLER.) 



Phylloscopus xanthodryas, Swinhoe, Proc. Zool. Soc. 1863, p. 296. 



Swinhoe's Willow- Warbler differs from its Japanese allies in having 

 all the underparts much suffused with yellow. 



The Japanese representative of the Arctic Willow- Warbler, better 

 known as Swinhoe's Willow- Warbler, breeds in the Kurile Islands, 

 ill "^^ezzo, and in the mountains of Southern Japan, migrating south- 

 wards in autumn. I have an example collected by Wossnesensky on 

 the Kurile Islands; there is an example in the British Museum 

 obtained by Capt. St. John at Hakodadi (Seebohm, Cat. Birds Brit. 

 Mus. V. p. 43) ; and there are eleven examples in the Fryer collection 

 from Fuji-yama. 



Swinhoe's Willow- Warbler is only known to breed in Japan, where 

 it is common. It passes the coast of China on migration and winters 

 in Borneo. 



37. PHYLLOSCOPUS TENELLIPES. 

 (PALE-LEGGED WILLOW-WARBLER.) 



Phylloscopus tenellipes, Swinhoe, Ibis, 1860, p. 53. 



The Pale-legged Willow-Warbler has very pale legs and feet. It 

 has two pale bars across the wing, and the 2nd primary is equal to 

 or slightly longer than the 7th. Like most of its allies it is olive- 

 brown above, but it differs from them in having the rump and upper 

 tail-coverts russet-brown. 



There is an undoubted example of this species in the British 

 Museum, which was formerly in the Tweeddale collection. It is 

 sexed a female, and was procured by Mr. Henry Whitely at Hako- 

 dadi on the 5th of May, 1865 ; and there is a second example in the 

 Paris Museum, procured by FAbbe Fauire in the same locality. 



The Pale-legged Willow-Warbler probably breeds in Japan and
