in the fir-forests; hence, in West Finmark, it is most abundant 

 in Alten, but has not been observed in théibirch woods along the 

 Porsangerfjord or in the neighbourhpod of Hammerfest. It affects 

 the birch woods mostly in winter, and has been repeatedly shot 

 on Tromsøen, where there is little probability that it breeds. It has a 

 similar distribution in the alpine districts of the south. Here it 

 abounds in the uppermost fir-forests of the Dovre and Langfjeld 

 and their ramifications, straying but rarely into the adjacent birch 

 woods, and it does not occur regularly beyond the fir region of 

 the fells. # 



An individual shot atBosekop, in Alten, July 14th 1872, mea- 

 sured as follows. Total length 133 rom; wing 65, tail 63, tarsus 

 18, middle toe 7 l / 2 -\- 5 mm. The call-note of this bird resembles 

 that of the Panis borealis, but each tone is briefer, less decided 

 in expression, and uttered more precipitately.

 Has not been found north of Salten (67° 10'), where it is 

 tolerably abundant. 1 



Hirundo ur bi ca, Lin. 



Colonies of this bird were seen in the valley of the Maalselv, 

 near Tromsø, and atBosekop, in Alten, June and July 1872. Not 

 observed in Porsanger; in East Finmark, it ranges as far north as 

 Vadsø, building in several localities both in the mountain-walls and 

 on the huts of the inhabitants. 



Hirundo ru sti ca, Lin. 



Not rare on Tromsøen in June 1872; in Finmark, it has been 

 observed in Alten, by Prof. Sundcvall. Individuals have also 

 been met with at Hammerfest, and it lias repeatedly been observed 

 in East Finmark, where it is known to have bred several times 

 (Nordvi and others), at Vadsø, for instance.
