Hah. — Northern North America, Wisconsin, (Dr. Hoy,) Canada, (Dr. Hall,) Western, (Prof. Lichtenstein.) Spec, in Mus. 
Acad. Philadelphia, and Nat. Mus. Washington. 
This is a species lost sight of by naturalists for upwards of half a century, and until brought 
to light through the researches of Dr. Hoy, of Racine, "Wisconsin, who is the only naturalist by 
whom it has been obtained within the limits of the United States. It has been noticed also by 
Dr. A. Hall in the vicinity of Montreal, Canada. It is given by Professor Lichtenstein in tbe 
Transactions of the Berlin Academy, as above cited, as a bird of California ; but he regards it 
as identical with N. acadica, and with reference to locality may allude only to the latter species. 
This bird is about the size of Nyctale acadica, but is quite distinct, and, in fact, bears but little 
resemblance to that species. We have no doubt that it is the true Strix albifrons, Shaw, as 
above cited. It is probably a northern and northwestern species.

Hub. — The whole of temperate North America. Spec, in Nat. Mus. Washington, and Mus. Acad. Philadelphia. 
This is the smallest owl found in the eastern and middle States of North America, and is 
probably an inhabitant of the entire temperate regions of this division of the continent. Speci- 
mens in the present collection are from Texas and from Washington Territory. We have 
known it to be found also in California, where very probably it is of as frequent occurrence as at 
the same latitude on the Atlantic.
