The Intermediate Sparrow was obtained by Xantus at San Jose del Cabo on 

 November 15, and at San Nicolas in October. Mr. Belding did not meet with 

 it, and Mr. Frazar took only four specimens, one at Triunfo on April 18, and 

 three at San Josd del Cabo, on October 13, and November 3 and 5, respectively. 

 From this it appears that in the Cape Eegion gambelii is much less numerous 

 than leucophrys, if not of positively rare occurrence. To the northward it was 

 not seen by Mr. Bryant, but Mr. Anthony found it in the northwestern part of 

 the Peninsula. Typical nuttalli has occurred on San Pedro Martir, about 

 Ensenada, and on Santa Margarita Island, but not as yet in the Cape 

 Region. 



Z. I. gambelii is an abundant winter resident in most parts of California, but 

 it is not known to breed south of Oregon, while its summer range extends into 

 Alaska. Mr. Frazar collected numerous specimens near the cit^^ of Chihuahua, 

 Mexico, in the autumn of 1888, but he found none south of Guaymas on 

 the west coast. These facts suggest that gainbelii, at all seasons, has a more 

 northern distribution on the Pacific slope than its near ally leucophrys. 



Spizella socialis arizonae Coues. 



Western Chipping Sparrow. 



Spizella socialis arizonae Belding, Proc. U. S. Nat. Mus., VI. 1883, 347 (Victoria 

 Mts.). Bryant, Proc. Cahf. Acad. Sci., 2d ser., II. 1889, 300 (Victoria 

 Mts.). 



Mr. Belding characterizes this .sparrow as "rather rare," and says that he 

 did not see it below 3000 feet altitude, both of which statements are confirmed 

 by the experience of Mr. Frazar, who obtained only a single sjjecimen, — a 

 male, killed on April 30, on the summit of the Sierra de la Laguna. Mr. Bryant 

 did not meet with the bird at all, but Mr. Anthony has found it " at lat. 31° N., 

 from the coast to 2,500 feet altitude " (Bryant) and about the base of San 

 Pedro Martir, where it is abundant and resident.^ It is rather common in 

 summer in most parts of California, and ranges northward to the Yukon
