4. Wing, 5.50-5.90 ; tail, 2.80-3.50. Varying to bright rufous ; gray phase like that 



of asio and floridanus, but the mottling above much coarser, and the nape 

 ■with a strongly indicated collar of rounded white spots, in pairs, on opposite 

 webs. Red phase much more spotted above than that of asio or floridanus. 

 Hab., E. Mexico and highlands of Guatemala /3. maccalli. 



5. Wing, 6.80-6.90 ; tail, 3.90-4.10. Not varying to rufous. General aspect much 



paler than any of the preceding ; above pale ash-gray, or very pale cinnamon- 

 gray, the white of the outer webs of the lateral scapulars very conspicuous, 

 the white spots of the outer webs of the primaries sometimes confluent. 

 Beneath pure white, much more sparsely marked than in asio and other races. 

 Hab., Mountains of Colorado e. maxwellice. 



The characters given above are sufficient to distinguish typical speci- 

 mens of several well-marked geographical forms of Scops asio. It is of 

 course understood that specimens possessing intermediate characters 

 frequently occur ; but it is equally true that a very large majority of the 

 specimens from either one of the regions indicated above are typical of 

 the form characteristic of the locality.
