1918] Swarth: The Pacific Coast Jays of the Genus Aphelocoma 417 
not known. The probabilities are that it does not, and that the birds 
that have been taken in the region in the autumn were wanderers from 
points farther east. However this may be, there is one specimen at 
hand from this section, taken at 5,500 feet elevation on Carroll Creek, 
Inyo County, that in color and markings exhibits a blending of the 
characters of the two forms. This bird, an adult male (no. 20068, 
September 9, 1911), is of a decidedly paler blue than are comparable 
specimens from the west side of the Sierras, while the dorsum is 
bluish gray, rather than brownish, as in the latter. Whiteness of 
under parts of body and lower tail coverts, the streakings upon the 
breast, and measurements and proportions, are all exactly as in 
immanis. This bird therefore must be classed with the latter form, 
but the dorsal appearance of the specimen is strikingly similar to fall 
examples of woodhousei, and quite different from any other specimen 
of immanis at hand. The nature of this departure from the usual 
coloration of immanis, occurring in a specimen from this particular 
region has undoubtedly some significance as regards the relationships 
of the two forms. For the present, however, I prefer to regard them 
as specifically distinet, for the same reasons as those advanced in the 
ease of the two species of Psaltriparus that occur here; the observed 
conditions are closely similar. (See Swarth, 1914, p. 521.) 
There are two breeding birds at hand from this section, taken near 
the east base of Kearsarge Pass in June (nos. 22504, 22505). The 
feathers are too abraded to be of service in color comparisons, but to 
all appearances these birds are typical of ammanis. 
Aphelocoma woodhousei (Baird) 
Type locality.—Fort Thorn, New Mexico. 
Range in California—Upper Sonoran zone in the desert mountains of the 
eastern part of the state, in the Inyo and Mohave regions. At the eastern 
base of the Sierra Nevada, probably as a transient only.

Total 44. . 
Distinguishing characters—Compared with any of the subspecies of Aphelo- 
coma californica, A. woodhousei differs in coloration and in proportions of bill. 
The blue areas are dull and pale, the back is strongly suffused with bluish gray,
