HAWK-OWL. 34,7 



Strix uralensis of Pallas. The Snowy Owl, Strix nyc- 

 tea of Linnajus, has a less accipitrine aspect, and other 

 species, as Strix passerina of Linnseus, having a pro- 

 portionally larger head and shorter tail, are more strict- 

 ly strigine. The latter species is very intimately al- 

 lied to Strix Tengnialmi, which may with more pro- 

 priety be referred to a different genus. 



Two species have been found in Britain, Syrnia nyc- 

 tea and Syrnia passerina, both very rare.
