T3^pical .spechnons of this race differ from adrnta, in tlie much less 
reddish back, as well as noticeably more pinkish nape and l)end of 
wing; from Ieuc(Uisi!j}tihi, besides much darker colors above, in more 
pinkish nape and more brownish back, these last two characters being 
those of most value in the determination of intermediates. Compared 
vfMh pallida^ aphrasta is nuich darker, particularly on the back and 
rump, with decidedl}^ less cinnamomeous tinge, this most conspicuous 
on occiput, cervix and bend of wing. It may be distinguished from 
amriiophlla by the more pinkish cervix, upper tail-coverts and bend of 
wing, together with the more uniform upper surface, the l)ack having 
usually less blackish; from nctla and eJirysolceina^ by much paler and 
more uniform upper surface. It is much larger and paler than oaxacce; 
decidedly smaller, as well as somewhat less deeply colored, than occl- 
dentalls; much smaller, more uniform, and more reddish above than 
leucoloima. 
The young of this race differ from those of aetla in their much paler 
coloration, this being especially noticeable on the top and sides of the 
head, ))ut these are by no means constant distinctions. From amino- 
pJiila and leucoUmm the difference, which consists of the decidedly 
deeper ochraceous on all the ui)per parts, is more marked. Compared 
with oaxacm and adusta the young of aphrasta are paler and somewhat 
more grayish. 
Breeding specimens from Willcox and Fort Bowie, Arizona, show an 
inclination toward leticolmma in the pallor of tlie occiput and nape, but 
undoubtedly should be called ap/irasta. Sulphur Spring and Willow 
Spring, Arizona, are also here included in the range of the present 
race, though it should be stated that this rests upon the determination 
of birds in first plumage. Breeding examples from San Diego, Chi- 
huahua, Mexico, seem to be essentially typical; as also a series from 
La Ventura, Coahuiia, though the males of the latter have the throat 
and eyebrow more deeply 3'ellow, and the back with more admixture 
of brown, producing a less uniform appearance. None of the avail- 
able specimens of this subspecies can certainly be said to have been 
taken out of its breeding range, and aphrasta^ probably is very nearly 
if not quite resident. An autumnal male from Parral, Chihuahua, 
Mexico, has a very deep yellow throat, this color also suff'using the 
entire head and slightly invading the breast below the black jugular 
crescent, this last, however, something which even breeding birds 
occasionally exhibit. Examples from the southwestern corner of New 
Mexico (Grant Count}^, etc.), are intermediate between leucolama and 
ajjhrasta, but appear to be nearer the latter. Occasional specimens 
from this region are almost indistinguishable from leucansiptila^ but 
have usualh^ somewhat darker backs. To the southward, in the State 
of Durango, Mexico (specimens from Durango City), the birds are 
more reddish again, approaching the appearance of adiista. Coming
