It differs in no respect, except in size, from North American examples ; it measures, wing, (t; tail, Hahits. This species, one of the smallest of our North American Owls, was first obtained on the Columbia liiver l>y Dr. Townsend, near Fort Vancouver; and subsequently. Dr. Merideth Gairdner procured several others from the same locality, which were sent to the Edinburgli ]Museuni. Dr. Townsend's specimen was said to have been taken on the wing at midday.
