the Yen-e-say’ Willow-Warblers winter in Persia, whence 
Blanford records them. 
In the St.-Petersburg Museum I had an opportunity of 
examining the type of Eversmann’s Sylvia icterina, which was 
afterwards rechristened by Bonaparte Phyllopneuste evers- 
manni. I found it to be a typical specimen of Phylloscopus 
trochilus. 
Puyxuoscopus Tristis, Blyth. 
The Siberian Chiffchaff arrived on the Arctic circle on the 
4th of June, and was a common bird there until we left. 
Even before the snow was melted in the forests its cheerful 
chivit’-chivet’ was constantly to be heard. When feeding it 
is a most restless bird, seeming always to be in a hurry, as 
if its object were to cover as much ground as possible. Later 
on in the season it was much less difficult to shoot. Although 
it arrives so early, it appears to be a late breeder. The first 
nest I found was on the 2nd of July in lat. 67°. We were 
taking in ballast after our second narrow escape from ship- 
wreck. I went on shore for a few hour’s shooting. Along- 
side the ship, on a grassy part of the river-bank, there were 
three Ost’-yak chooms, with a herd of about fifty reindeer. 
Fifty yards above this encampment the shore was very muddy, 
and between the river and the forest was a long gently sloping 
bank sprinkled over with willows. In these trees wisps of 
dry grass were hanging, caught between the forks of the 
branches, and left there after the high water had subsided. 
In one of these, about two feet from the ground, a Siberian 
Chiffchaff had built its nest, or rather it had appropriated one 
of them for its nest. There was scarcely any attempt at 
interlacing stalks. It was undoubtedly the most slovenly 
and the most loosely constructed nest I remember to have 
seen. It was scarcely more than a hole, about two and a half 
inches in diameter, with one side a little higher than the other. 
The entrance was somewhat smaller than the greatest size 
inside, which was very globular and carefully lined with Caper- 
calsie and Willow-Grouse feathers, plenty of which would 
naturally be found so near to an Ost’-yak choom. I shot
