186 THE NATUEALIST IN NOEWAY. 



Richardson's skua (L. Richardsonii) . Common all 

 along the Norwegian coasts. Professor Rasch, of the 

 University of Christiania, says he once shot two male 

 birds and a female of this species by the side of a 

 small inland sea near Mandal, in the south of Norway. 

 This bird preys on young gulls, on which account it is 

 called in Norway the jo-tyv, or jo thief. 



Buffon's skua (L. Buffonii). This species is com- 

 mon in Swedish and Norwegian Lapland. It is seen 

 in the Dovre-fjeld, as well as in the mountains of Lap- 

 land, on which account it is called in Sweden the 

 fjall-lalbe, or mountain mew. Professor Esmark in- 

 forms me that this species breeds in Finmark, where 

 it makes its nest by the sides of small inland lakes.
