lower abdomen and flanks. It is larger than Scops enano [i. e., maccalli], 

 and differs from that bird also in not having a rufous phase; the cross- 

 barring of the under surlace in the latter is of the same character in 

 S. enano as in 8. asio : that is to say, the bars are often double, whereas 

 in S. trichopsis they are single and very distinct." 



The specimens in the British Museum, two in number, are both from 

 "Western Mexico; and it would seem that the species is mainly confined 

 to the Pacific slope of that country, though ranging sparingly into the 

 Southwestern United States, where, however, true S. asio is much 

 more common.
