named and recognized allies. Mr. Frazar’s specimens appear to represent two 
forms, —a small, slender-billed one which I take to be typical alaudinus, and 
a decidedly larger bird, which has a bill nearly as stout as that of savanna. 
Mr. Frazar found the Western Savanna Sparrow in winter at La Paz, in 
autumn at Santiago and San José del Cabo. At the locality last named his first 
specimen was taken on August 27. During the next three weeks it was rather 
common, frequenting wet, grassy places. Mr. Bryant mentions seeing it only 
at San Jorge, where a few birds were observed in April. Mr. Anthony states 
that ‘‘a few winter about the base of San Pedro [Martir].”?} 
This subspecies occurs almost everywhere along the Pacific coast from north- 
western Alaska to southern Mexico, breeding from California northward.

Although the Large-billed Sparrow is not mentioned in Mr. Frazar’s notes, 
he must have found it in considerable numbers, for’ his collection contains no 
less than fifty-five skins, of which four were obtained at La Paz in January 
and February, sixteen at Carmen Island in early March, and thirty-five at San 
José del Cabo at various dates between August 31 and November 9. All the 
specimens thus far collected in the Cape Region have been taken in autumn, 
winter, or early spring. Indeed, there is no present evidence that the bird 
breeds anywhere in Lower California. Mr. Bryant met with it only in Feb- 
ruary, 1888, when a few were found “among the bushes on the sand hills near 
Magdalena village,” and Mr. Anthony does not seem to have seen it at all. 
According to Dr. Cooper, it is found abundantly at all seasons at San Diego 
and San Pedro, California. At the latter place he “saw them, in July, feeding 
their young.”? Mr. Belding, referring to this statement, says, ‘I could not 
find the species about San Diego Bay or False Bay in April and May, 1881, 
nor in April and May of the years 1884 and 1885, in the latter year having 
followed the coast nearly fifty miles north of San Diego without finding it. I 
last saw it at San Diego, March 10, 1884. Its nesting places and nesting habits 
are still unknown.” 
I have two specimens of A. rostratus taken at Guaymas on the western 
coast of Mexico.
