XXVII.— Further Notes on Phylloscopus borealis in Nonvay. 
By Robert Collett, F.M.B.O.U. 
In the ‘ Proceedings 9 of the Zoological Society of London for 
1877, p. 43, I published some observations on Phylloscopus 
borealis and its occurrence in Norway. I had found this 
species during the summer of 1876 established in several 
places in Finmark, as in the inner valleys of Porsanger 
and in the valley of the Pasvig river in South Varanger. 
Since then I have visited Finmark on several occasions 
during the summer, and have frequently had opportunities of 
observing P. borealis in the previously known spots, as well 
as in fresh localities. I therefore wish to make some further 
observations concerning this interesting species as a supple¬ 
ment to my former paper. 
Phylloscopus borealis is to be found breeding in Finmark 
(Norwegian Lapland) in many of the luxuriant birch-woods 
both in West and East Finmark. To the west of the North 
Cape I have not met with it up to the present, nor espe¬ 
cially in the rich valleys in Alten, which, however, I have 
had but little opportunity of visiting; but I believe it not 
unlikely that it will be found inhabiting this district also, 
and thus prove that it has extended its range to the western
