sixth ; bastard primary measuring 0'5 to 0'6 incli. Length of wing, 

 male 2-84 to 2-7 inches, female 2-7 to 2-6 ; tail, male 2-1 to 1-95, 

 female 1*95 to 1'8 ; culmeu 0-51 to 0-;')5 ; tarsus 0-8. 



The changes of plumage in this species are similar to those of the 

 preceding species, but at all seasons of the year the general colour 

 of the underparts is much paler in colour in P. horealia (Blasius). 

 The smaller size and smaller bastard primary of the latter species 

 serve, however, to distinguish even birds of the year from the 

 present species, though they approach each other very closely. 



Swinhoe's Willow- Warbler is said j;o breed in Kansu and Japan. 

 It passes through South-east China on migration, and winters in 

 Borneo.
