The Intermediate Sparrow was obtained by Xantus at San José 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 José del Cabo, on October 13, and November 3 and 5, respectively. 
From this it appears that in the Cape Region gambelit is much less numerous 
than lewcophrys, 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 nuttallc has occurred on San Pedro Martir, about 
Ensenada, and on Santa Margarita Island, but not as yet in the Cape 
Region. 
Z. 1. gambelit 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 city of Chihuahua, 
Mexico, in the autumn of 1888, but he found none south of Guaymas on 
the west coast. These facts suggest that gambeliz, at all seasons, has a more 
northern distribution on the Pacific slope than its near ally leucophrys. 
Spizella socialis arizonae Covss. 
WESTERN CHIPPING SPARROW. 
Spizella socialis arizonae BELpING, Proc. U. S. Nat. Mus., VI. 1883, 347 (Victoria 
Mts.). Bryant, Proc. Calif. 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 specimen, —a 
male, killed on April 30, on the summit of the Sierra dela 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
