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

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

 Porsangerfjord or in the neighbourhood of Hammerfest. It atfects 

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

 on Troms0en, 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 1873, mea- 

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

 18, middle toe 7V2 + ^ ™™- The call-note of this bird resembles 

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

 in expression, and uttered more precipitately. 



Acredula caudata, Lin. 



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

 tolerably abundant.^ 



Hirundo urbica, Lin. 



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

 near Troms0, and atBosekop, in Alten, June and July 1872. Not 

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

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

 on the huts of the inhabitants. 



Hirundo rtistica, Lin. 



Not rare on Troms0en in June 1873 ; in Finmark, it has been 

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

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

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

 (Nordvi and others), at Vads0, for instance. 



Hirundo rip aria, Lin.. 

 Is the commonest species north of the Arctic Circle, and breeds, 

 in suitable localities up to the Russian frontier. Colonies of these
