246 DR. J. J. KAUP’S MONOGRAPH OF THE STRIGIDA. 
Subgenus b. Sériz. 
Diagn.—Of middling size and very lightly built. The first wing-feather nearly as 
long as the second, the third a little shorter. Only the first wing-feather on the end 
of the inner web feebly emarginated. Toes finely scaled, and provided with bristle- 
feathers. The long wings reach beyond the short tail. 
The members of this subgenus all bear very near relation to each other, and we have 
for a long time considered them as climatic varieties of the common Strix flammea. 
They are spread over the whole world.
