Astragalinus psaltria breeds abundantly in California, especially in the 
central portions, but does not appear to go much further northward. It visits 
northwestern Mexico in winter. 
Astragalinus psaltria arizonae (Cougs). 
ARIZONA GOLDFINCH. 
This form is represented in Mr. Frazar’s collection by a perfectly typical 
specimen —a male taken at San José del Cabo on October 31, 1887. It has 
not been previously reported from any part of Lower California, although it 
has occurred once before on the Pacific Coast (Haywards, Alameda county, 
California!). I have long entertained doubts regarding the wisdom of recog- 
nizing it as subspecifically distinct from psaltria. It is true that the two are 
sufficiently unlike to be distinguished at a glance, but they intergrade and do 
not appear to have separate habitats. Thus from southern Arizona and New 
Mexico and northern Mexico, the supposed home of arizonae, my collectors 
have invariably sent me at least a dozen specimens of psaltria to one of arizonae. 
Indeed, there seems to be no known region or locality which yields exclusively 
or even chiefly the so-called arizonae. These facts suggest that the latter name 
applies merely to aberrant specimens of psaltria which represent more or less 
well marked approaches to the wholly black-backed A. p. mexicanus, or, as 
Mr. Ridgway has lately put the case, that arizonae “ is scarcely a definite form, 
but is rather a series of specimens connecting A. p. psaltria and A. p. mext- 
canus, hardly two examples being exactly alike, and the geographic range not 
very definite.” 2

Mr. Belding’s mention of ‘‘ one observed . . . in a flock of A. psaltria, with 
which, in California, the species frequently associates ” remains the only record 
for the Cape Region. Neither date nor locality is given in this connection, 
but in his Land Birds of the Pacific District * Mr. Belding states that “a 
single specimen,” presumably the one just referred to, was “ shot at La Paz, in 
Lower California, in the winter of 1882.” 
On San Pedro Martir, according to Mr. Anthony, the Pine Siskin is “ well 
distributed through the pines... but undoubtedly not common; no nests were
