XXVII. — Further' Notes on Phylloscopus borealis in Norivay. 

 By Robert Collett, F.M.B.O.U. 



In the ' Proceedings ' 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
