Fi Mr. H. Seebohm on the Ornithology of Siberia. 
Cyanecuxa surecica (Linn.). 
I found the Blue-throated Warbler very common in the 
valley of the Yen-e-say’. It was amongst the earliest insect- 
eating birds to arrive at our winter-quarters. I shot several 
on the 5th of June. For a week or two they were very com- 
mon ; but as the snow on the tundra melted they gradually 
left us, only a few remaining to breed. I lost sight of the 
Blue-throat in lat. 71°. 
Nemoura cyanura (Pall.). 
Curiously enough the first Warbler I shot on the Yen- 
e-say’ was the Blue-rumped Warbler. It was, of course, 
only an accidental straggler, who had strayed away from his 
companions and reached the Arctic circle before his time. 
It was the 21st of May, a bitterly cold day, no sunshine, a 
sou’-west wind, but nevertheless a keen frost. I did not turn 
out in the morning; but in the afternoon I put on my snow- 
shoes and had a round through the forest. There was hardly 
a bird to be seen ; but as I was returning to the ship I caught 
sight of a little bird flitting about from tree to tree, apparently 
seeking insects on the trunks below the level of the surface 
of the snow in the hollows round the stems, caused by the 
heat of the sun absorbed by their dark surfaces. It gave me 
a long chase, flying rapidly, but never rising higher than three 
or four feet above the level of the snow. At last I got a 
long shot at it. It was alive when J secured it; and I re- 
marked its brilliant, large, pale, blood-red eye. ‘The legs 
were brown, and the bill nearly black. I shot a second ex- 
ample on the 14th of June; it was busily engaged in search- 
ing for insects, principally at the roots of trees. This was 
all I saw of this bird. Both my birds are males, but not in 
the fine metallic blue plumage which old birds attain. I was 
probably at the extreme limit of this bird’s northern range. 
CALLIOPE CAMTCHATKENSIS (Gmel.). 
I only met with this very handsome bird once within the 
Arctic circle. This was on the 14th of June, whilst the ice 
was still straggling down the river. Early in the morning, 
before breakfast, Blue-throats were singing lustily. One bird
