PHYLLOSCOPUS SUPERCILIOSUS (Gmel.). 
On the 4th of June, while the ill-fated ‘ Thames’ was in 
the agonies of its first shipwreck, I was delighted to have my 
attention called away by the note of this interesting bird, 
which I recognized at once as the same which I had heard 
in Gaetke’s garden on Heligoland the year before. It is 
very fairly represented by the word weest. The bird soon 
became very common, frequenting almost exclusively the 
pine-forests on the banks of the Koo-ray’-i-ka and the Yen- 
e-say’. It was not particularly shy ; and on more than one 
occasion I watched it for some time at a distance of only a 
few feet. On one occasion only I heard it make any attempt 
at a song; this was on the 2lst of June. The bird was 
perched upon the extreme summit of a spruce, and stood 
shivering its wings, uttering a few plaintive notes, most of 
them poor and feeble variations on its call-note. On the 
26th of June I was fortunate enough to find its nest. Curi- 
ously enough I was this time also in company with a Heligo- 
lander, Mr. Boiling, the ship-builder of Yen-e-saisk’. Late 
cage 0 the evening we were strolling through the forest between 
“the Koo-ray’-i-ka and the Yen-e-say’. As we were walking 
along a little bird started up near us, and began most per- 
sistently to utter the well-known cry of the Yellow-browed 
Warbler. As it kept flying around us from tree to tree, we 
naturally came to the conclusion that it had a nest near. 
We searched for some time unsuccessfully, and then retired 
to a short distance, and sat down upon a tree-trunk to watch. 
The bird was very uneasy, but continually came back toa 
birch tree, from which it frequently made short flights to- 
wards the ground, as if it was anxious to return to its nést, 
but dare not whilst we werein sight. This went on for about 
half an hour, when we came to the conclusion that the nest 
must be at the foot of the birch tree, and commenced a second 
search. In less than five minutes I found the nest, with six 
eggs. It was built in a slight tuft of grass, moss, and bil- 
berries, semidomed, exactly like the nests of our Willow- 
Warblers. It was composed of dry grass and moss, and lined 
with reindeer-hair. The eggs were very similar in colour to-_
