 El Paso region of extreme Avestern Texas; south into northeastern corner of 

 Lower California and to Guaymas, Sonora (A. O. U. Check-list, 1910, p. 137). 



Distribution in California — Abundant resident locally, almost ahvays in the 

 near vicinity of streams or springs, on both the Colorado and Mohave deserts. 

 Recorded north to Amargosa and Death valleys (A. K. Fisher, 1893a, p. 29) ; 

 Avest across the Mohave Desert to Heeperia (Thurber, 1896, p. 265), on the Col-

 captiAdty, from Los Angeles, San Bernardino, and other points on the Pacific 

 slope of southern California. Along the AATstern edge of its range, this quail 

 occurs at many points on common ground Avith the Valley Quail, and hybridization 

 is knoAvn to occur.

 to the deserts of the southwest. It is to be found from extreme south- 

 ern Colorado and the western extremity of Texas westward to south-
