This Owl has much the appearance of S. guatemalce, with which Dr. Sharpe, in 

 his Catalogue, placed a specimen from Nicaragua which undoubtedly belongs here. 

 It may at once be distinguished from that species, and all the members of the 

 S. brasilianus section of the genus, by its toes having scattered bristly feathers over 

 their upper surface. 



We have now seen six specimens of S. cooperi, including one lent us by Mr. Ridgway 

 and named by him. They are almost exactly alike in their general tint and in the 

 size and character of the dark markings. 



The most northern locality we have for this species is the Isthmus of Tehuantepec, 

 whence Sumichrast sent us a specimen shot on January 7, 1880. It is named "Scops 

 maccalli" which name was doubtless changed to S. trichopsis in the list of Mexican 

 birds published in ' La Naturaleza.' A note on the label of this bird states that the iris 

 is yellow, and the digits dull yellow.
