The Snowy Owl is not an uncommon visiter among us, and is considered the harbinger of 
a severe winter. He seems to be gregarious in his migrations, if not in habits; for his ap¬ 
pearance in this vicinity is always in considerable numbers at a time. He is diurnal as well 
as nocturnal, and feeds on fish and the smaller quadrupeds. The Snoiv Owl is abundant in 
Maine and Massachusetts, and may possibly be found to breed in the most northerly parts of 
this Stale. He has been seen in Florida, and has also been observed as high as the 75lh 
degree of north latitude. 
This species has been separated from Surma by the Prince of Canino, and placed under 
a genus Nyctea.. Of this genus, which he has not characterized, I find no account. It 
certainly exhibits variations from the typical form, in the more distinct disk, shorter legs, 
prominent eyebrow's, and small ear-apertures ; but for the present w'e arrange it as above. 
The adoption of the specific name Candida of Latham by the Prince, seems to follow fiom 
the generic change. The Snowy Owl is found in the northern parts of both continents.
