sometimes ranging in the mountains as high as the border of tree 
growth, and it is also to he met with in the bush-covered valleys 
(iodlevski says that its call-note, which is seldom repeated, may be 
rendered as tsii, shriller and more prolonged than the call-note of 
P. auperrilioms, and the song of the male, which is continued for 
hours without intermission, is melodious and varied, and of a very 
high order. Dr. Dybowski also writes (J. F. O., 1872, p. 301), 
that “its note is melodious and powerful, and its song varied and 
sweet, and so loud that it rings through the forest, and is 
astonishing as coming from so small bird.” Mr. W. E. Brooks, 
who has had frequent opportunities of hearing the call-note of 
this Warbler, says (‘Ibis,’ 1809, p. 230) that “it is very different 
from that of P. xitperciliosux, and is extremely shrill, feeble, and 
tinkling. There are two notes in the call, the second considerably 
above the first, I) to F sharp ; and in uttering its call the bird 
keeps the two notes quite distinct, and not slurred into each other, 
like the call of P. superciliosus.” Of the rarer Eastern Warblers 
which have occurred in Great Britain, Pallas’s Willow Warbler most 
nearly resembles the Yellow-browed Warbler, but differs widely 
from that species in having a conspicuous lemon-yellow stripe 
passing from the base of the bill along the centre of the crown to 
the nape, besides having the two superciliary stripes as in the 
Yellow-browed Warbler. It has also two conspicuous pale 
sulphur bars crossing the wing, and the rump is bright sulphur 
yellow. 
It may not be out of place here to add a few remarks on other 
Eastern Warblers, which have strayed as far west as the British 
Islands. Of these the Yellow-browed Warbler, Phylloscopus 
mpercil iosux (Omel.), has occurred most often, and one was obtained 
at Clcy, Norfolk, as recently as the 1st October, 1894. Another 
Eastern Warbler which has lately been added to the British list, 
is the Greenish Willow Warbler, Phylluscopux viridanus, Blyth, 
a single example of which was obtained at North Cotes, Lincoln- 
shire, on September 5th, 1896, by Mr. G. H. Caton Haigh. This 
Warbler inhabits the Altai range, Turkestan, the Himalayas, 
Eastern European Russia, and in all probability the Caucasus. It 
is said to be common in the Perm Government, and it also inhabits 
during the summer season those of Olonetz, Jaroslaf, and 
Orenburg. That it breeds in the Perm Government is certain, as
