BIRDS OF THE PACIFIC DISTRICT. 171 



Ridgway. Met with only in the ravines of the Sierra 

 Nevada near Carson and Washoe. It was entirely ab- 

 sent during the winter, not arriving from the south until 

 about the 20th of April. It was particularly numerous 

 in the lower portion of the mountains. 



Henshaw, 1879. Present along much of the eastern 

 slope and probably reaches quite to the Columbia River. 

 I think it never descends into the lower valleys, which 

 seem to be preferred by the allied form, P. schistacea. 



193. Passerella iliaca schistacea (Baird). SLATE-COL- 

 ORED SPARROW. 



Poway. F. E. Blaisdell. Specimen taken April 19 

 (identification correct). 



Murphys. L. B. January 4, 1879, one specimen 

 (No. 77081, Smithsonian collection). 



Ridgway. Carson. First met during its northward 

 migration, which began late in February or early in 

 March; some few individuals having doubtless remained 

 during the winter. The following September it was ob- 

 served in the Upper Humboldt Valley. 



Camp Harney. Bendire. A common summer visi- 

 tor; arrives about April 1. I have found some twenty 

 nests within half a mile of the post. 



194. Pipilo maculatus megalonyx (Baird). SPURRED 

 TOWHEE. 



San Diego, common resident. L. B. 



Santa Catalina Island. F. Stephens. August, 1886, 

 abundant. 



Poway. F. E. Blaisdell. Common resident. 



Volcan Mountains. W. 0. Emerson. Seen in every 

 walk. 



San Bernardino. F. Stephens. Common resident of 

 valley, foothills and mountains. Agua Caliente, in 

 canons, probably resident.
