 Naum. Taf. 42, fig. i, Susem. Vog. Eur. Taf. 42. 



Nyctale Brehm, Scotophilus Swains. (Characters almost of tlie 

 preceding genus, but the opening of nostrils is smaller, and furnished

 Blas. Two tufts of feathers at the sides of forehead, standing- 

 out like ears. Auricular aperture large, lunate. Wings long,

 51 ; the short-eared oivl, la chouette; Europe, N. Africa, some parts of Asia 

 (and North America?); the ear-tufts, consisting only of two or three 

 plumules, are small and, since they are not always erect, readily escape 

 notice; they are placed close together on the top of the head; it is an 

 incorrect statement that they occur only in males. 



++ Facial disc incomplete, deficient above the eyes. 



Bubo Cuv., Asio Swains. Aperture of ears moderate, lunate. 

 Two tufts of longer plumes standing out at the sides of forehead.

 figured in Wilson Am. Ornith. PI. 53, fig. 3.
