CARPODACUS. 391 
streaks on lower parts narrower and less distinct, and wing-coverts 
tipped with dull buffy. 
b'. Bill from nostril not more than .35, its depth at base not more than .35; 
tarsus not more than .70. 
c’, Adult male with the red absolutely restricted within very definite and 
sharply-defined limits, its area including only the forehead and a 
broad superciliary stripe (reaching back to occiput), the malar 
region, chin, throat (sometimes chest also), and rump; its tint a 
very intense carmine or crimson. Otherwise, not obviously different 
from true C. frontalis. Wing (male) 3.05-3.10 (3.08), tail 2.60-2.80 
(2.70). Hab. Eastern and southern Mexico (Vera Cruz, ete.). 
C. mexicanus (MULL.). Crimson-fronted House Finch.! 
c’, Adult male with the red spreading at least over breast (sometimes over 
whole lower parts, except anal region and lower tail-coverts, and 
occasionally even tingeing the latter), and also invading, more or less, 
the crown, hind-neck, back, etc.; or else, if absolutely restricted 
within very definite limits, the tint not an intense carmine or crim- 
son. Length about 5,75-6.25, wing (male) 2.85-3.30 (3.08), tail 
2.40-2.80 (2.57). Eggs 80 x 55. Hab. Western United States, 
from Rocky Mountains to Pacific coast (chiefly south of 40° in 
the interior), and south through western and central Mexico to 
Colima and Guanajuato; Lower California. 
519. C. mexicanus frontalis (Say) House Finch.” 
6. Bill from nostril .40, or more, depth at base .40, or more, tarsus .75, or 
more. 
In plumage similar to ©. frontalis (verus), but darker; length about 
6.00-6.50, wing 3.10-3.35 (3.27), tail 2.60-2.90 (2.83), bill from nos- 
tril .40-.45 (.43), depth of bill at base .40-.50 (.46), tarsus .75-.85 
(80). Hab. Guadalupe Island, Lower California. 
520. C. amplus Ripew. Guadalupe House Finch.

2 After a very careful comparison of more than a hundred adult males (in red or partially red plumage), I 
am now quite convinced that the supposed race named Carpodacus rhodocolpus by CaBants (519a. C. frontalis 
rhodocolpus, Crimson House Finch, of the A. 0. U. Check List) is entirely untenable. The easily recogniza- 
ble differences of color (maximum extension of the red) which have led to its recognition prove to be, in the 
light of this abundant new material, not correlative with locality, as supposed, but are evidently an individual 
peculiarity, perhaps dependent upon age. Iam not at all certain, however, that the Lower-Californian bird 
should not be separated. A considerable percentage of the specimens which I have been able to examine are 
s0 peculiar that nothing approaching them can be found in the very large series from other localities. These 
peculiarities consist, (1) in the smaller general size, (2) rather more swollen bill, and (3) greater extension 
of the red. This last peculiarity is carried to such an extreme that in all of the “Cape St. Lucas” specimens 
the under tail-coverts are deeply tinged with pink, while in some even the wing-bands are pinkish; in several 
the pure deep madder-pink of the breast is continued backward over the belly and flanks, where the usual 
dusky streaks are entirely obliterated. From the insufficient material at my command I am unable to form a 
decided opinion in the matter, but the indications appear very strong that a local race, peculiar to the southern 
portion of Lower California, will eventually have to be recognized, in anticipation of which I propose the name 
Carpodacus mexicanus ruberrimus.
