of the specimens which are referable to this form, from 

 localities east of the mountains, represent it in its typi- 

 cal condition. 



Camp Harney. Bendire. An abundant species, but 

 less abundant than A. phteniceus. The eggs of these 

 two species present but little difference. As a general 

 thing the eggs of this form are not marked so much, and 

 a few are unspotted. 



Ridgway. East of the Sierra Nevada, found only in 

 the western depression of the Great Basin (Western Ne- 

 vada), and was there very rare compared with A. phue- 

 niceus. Specimen, Carson, March 9, 1868. Nest and 

 eggs, Truckee Reservation, June 3. 



Stockton. L. B. April, 8, 1879, first nest and full 

 set of eggs; young able to fly May 20, 1878.

 suitable localities. L. B. 



Bernardino River. F. E. Blaisdell. A colony breed- 

 ing May 16, 1883; May 25 all had hatched, four birds in 

 each nest. The young seemed to be of about the same 

 age. 



San Bernardino. F. Stephens. Common; breeds in 

 the valley. 



Cooper, 1870. I found them the most abundant spe- 

 cies near San Diego and Los Angeles, and not rare at 

 Santa Barbara.

 San Joaquin Valley from the Mojave Desert.
