Ridgway. In the rich valley of the Lower Truckee 

 the only species of hummingbird found in August at 

 which time great numbers were seen. Same locality in 

 May and June of the following season not one of this 

 species was found, its place being taken, apparently, 

 by T. alexandri. We next saw the rufous-backed hum- 

 mer in the West Humboldt Mountains. Eastward seen 

 only in Secret Valley the most eastward point to which 

 it is known to extend.
