Flats and Mt. Waterman,” where full-grown young were obtained on July 3, 
1897,1 and Mr. Belding has found it ‘ July 1 on Castle Peak, Nevada County, 
up to 8,000 feet,’ where it doubtless breeds.2_ In Mexico it occurs plentifully 
in winter and early spring near the city of Chihuahua, and it has been taken 
still further south, in Durango. I have specimens shot at Oposura, Sonora, 
but none from the west coast south of Guaymas.

The specimens taken in Lower California by Mr. Frazar appear to be pecu- 
liar only in respect to their bills, which are somewhat broader than in the 
birds which breed in southern California, 
The Black-chinned Sparrow is apparently of rather uncommon occurrence 
in the Cape Region, where it was first detected by Mr. Belding, who, in the 
winter of 1882-83, saw a single bird in the mountains, and afterwards, near 
Pescadero, a small flock, from which a single specimen was obtained. Mr. 
Frazar took two at La Paz in February, and six at Triunfo in April, the latest 
on the 23d of the month. To the northward, according to Mr. Bryant, it 
was found by Mr. Belding in May, 1885, between San Rafael and San Pedro 
Martir, but nowhere numerously, and by Mr. Anthony on San Pedro Martir 8 
and at Valladeres. At the place last named ‘‘they were common and nest- 
ing” (Bryant). It is not impossible that a few pairs breed in the Cape Region, 
also, but this remains to be proved. 
This Sparrow has been found in summer at a number of localities in southern 
California, where, according to Mr. F. Stephens, it nests in chemisal brush on 
steep hillsides at between 1,000 and 3,000 feet altitude. It has occurred as far 
to the northward as Inyo county in the interior of the State and in Alameda 
county near the coast. It is said to have a wide range in Mexico, but a single 
bird shot by Mr. J. C. Cahoon at Oposura, Sonora on May 10, 1887, is the 
only specimen which my collectors have obtained in that country.

3 Mr. Anthony has since reported that near San Pedro Martir the species is 
“rather common in the hills from the coast to the base of the mountain,” and that 
he is ‘“‘ sure that its song was heard in May, 1887, at 10,000 feet elevation.” Zoe,
