34. PHYLLOSCOPUS CORONATUS. 



(TEMMINCK^S CROWNED WILLOW-WARBLER.) 



Ficedula coronata, Temminck and Schlegel, Fauna Japonica, Aves, p. 48 (1847), 



Temminck's Crowned Willow- Warbler differs from the other 

 Japanese Willow-Warblers in having a pale mesial line on the crown^ 

 and in having the under tail-coverts bright yellow^ in strong contrast 

 to the rest of the underparts, which are nearly white.

Temminck's Crowned Willow-Warbler is a very common summer 

 visitor to all the Japanese Islands. Dr. Henderson obtained it at 

 Hakodadi in October 1857 (Cassin, Proc. Acad. Nat. Sc. Philad. 

 1858, p. 193), and I have several examples from the same locality 

 (Whitely, Ibis, 1867, p. 197). There are thirteen examples in the 

 Pryer collection from Yokohama, and JVTr. Jouy found it on Fuji- 

 yama in July (Jouy, Proc. United States Nat. Mus. 1883, p. 282). 



Temminck's Crowned Willow- Warbler breeds in Eastern Siberia 

 as well as in Japan, and passes along the coasts of Formosa and 

 China on migration, to winter in the islands of the Malay Archi- 

 pelago. 



35. PHYLLOSCOPUS BOREALIS. 



(ARCTIC WILLOW-WARBLER.) 



Phyllopmwste horealit, Blasius, Naumannia, 1858, p. 313. 



The Arctic W illow- Warbler diifers from its Japanese allies in 

 having a very small and pointed bastard primary, and in having the 

 underparts nearly white, very slightly tinged with yellow on the 

 breast and under tail-coverts.

The Arctic Willow- Warbler passes the Japanese coasts in spring 

 and summer on its migration from its breeding-grounds in Kamt- 

 schatka to its winter-quarters. I have an example collected by 

 Wossnesensky on the Kurile Islands, and it has been obtained in 

 Yezzo, but appears to be rare (Blakiston, Am. List Birds of Japan, 

 p. 56). There is an example in the Pryer collection from Yoko- 

 hama; and there is one in the Leyden Museum from Nagasaki 

 (Blakiston and Pryer, Trans. As. Soc. Japan, 1882, p. 159). 



The Arctic Willow- Warbler breeds in the Arctic Regions from
