Victoria Mountains (opposite Carmen Island) in early March. The bird 
appears to be chiefly confined to the foot-hills of the mountains, and to 
the arid region lying between them and the coast, for neither Mr. Belding 
nor Mr. Frazar found it on the Sierra de la Laguna. The former observer men- 
tions it among the species which he noted along the Pacific coast between 
Cape St. Lucas and a point thirty miles to the northward of Todos Santos. 
Mr. Bryant states that it is “common near La Giganta (San Pedro and San 
Julio plains),” and that Mr. Anthony met with it “ from Ensenada southward, 
up to an altitude of 6,000 feet . . . usually in mesquite thickets.” 
The Phainopepla is a common resident of most of southern California as 
well as of the greater part of Mexico.

Mr. Belding asserts that this form is ‘‘common” in the Cape Region, but 
Mr. Bryant omits it altogether from his catalogue, and cites Mr. Belding’s 
mention under gambeli. Mr. Frazar’s collection, however, contains two unmis- 
takable specimens of excubztorides, both males taken at Triunfo on December 
12 and 14 respectively. Hence the “ white-rumped” bird must be restored 
to the list; but whether it breeds in this region or visits it only in winter, 
remains to be ascertained. It “occurs in the eastern and sometimes also 
the central portions ’’ of California, while gambeli “belongs chiefly to the 
coast district”? of that State, according to Mr. Ridgway, as quoted by Mr. 
Keeler.!- I have numerous winter specimens of excubitorides from Guaymas 
and Alamos, western Mexico, and others have been taken at Mazatlan.
