BUFFON'S SKUA. 
Lestris Buffonii. 
PLATE CXLIII. Fia. I. 
The eggs of Buffon's Skua, several of which have 
been received from M. Holboell, do not differ from those 
of Richardson's skua. 
This species breeds in Greenland upon the pastures 
and moorland, but never in society, like the L. Rich- 
ardsonii.
