logical writers. Examination of the material available shows that 
it is, however, a recognizable subspecies, differing from Baolophus 
inornatus inornatus in its more grayish coloration and additionally 
in its darker under parts; and from Baeolophus inornatus griseus 
in its decidedly darker color. It ranges in the Pacific coast region 
from northern Lower California north through southern California 
to Santa Barbara County. 
Beolophus wollweberi annexus (Cassin). 
The existence of two forms of Beolophus wollweberi (Bonaparte) 
was first noticed by Mr. Ridgway. His distinction has subse- 
quently been ignored and the entire species included under one 
form. That there are, however, two readily distinguishable races 
is evident on comparison of specimens from Arizona with those 
from central and southern Mexico. The northern race differs 
from the southern in its decidedly paler coloration both above and 
below. 
This species was originally described as Lophophanes wollweberi 
from Zacatecas, Mexico, by Bonaparte.? Birds examined from 
Huasamota, Durango, which is considerably north of Zacatecas, 
prove to be almost identical with those from southern Mexico, 
though verging slightly toward the northern race; consequently 
the specific name wollweberi must apply to the southern bird, 
which, therefore, becomes the typical race. A name for the north- 
ern bird is, as already shown by Mr. Ridgway, found in Parus 
annexus Cassin,’ described from a specimen purporting to be from 
the Rio Grande in Texas. As, however, the species is not known to 
occur in Texas, this locality is probably erroneous; but the applica- 
bility of the name is undoubted, since the type, which has been ex- 
amined, proves to be identical with birds from Arizona. The 
northern race of the species must, therefore, stand as Beolophus 
wollweberi annexus (Cassin). Its geographic distribution is as 
follows:
