Victoria Mountains (opposite Carmen Island) in early March. The bird 

 appears to be chielly conhned to the ioot-hills of the mountains, and to 

 tiie arid region lying between them and the coast, for neither Mr. Beklin" 

 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 Pacihc coast between 

 Cape St. Lucas and a point thirty miles to the northward of Todos Santos. 

 Mr. Bryant states that it is " c(jmmon near La Giganta (San Pedro and San 

 Julio plains)," and that Mr. Anthony met with it " from Ensenada southward, 

 up to an altitude of (5,000 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 excubitorides, 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.
