BIRDS—CORVIDAE—CYANOCITTA WOODHOUSEIIL. 585 
crescent, white streaked with blue; behind it dull white; the sides tinged with brown. Length, 12.25; wing, 5; tail, 6.15; 
tarsus, 1.55. (2841.) 
Hab.—Vacific coast from Columbia river south. Not in the interior. 
The forehead and nasal feathers are uniform blue with the crown. The blue extends on the 
fore part of the back ; it is scarcely found on the rump, although the upper tail coverts are like 
the crown. There is no trace of blue on the belly, although a very faint wash is perceptible on 
the lower tail coverts. The blue streaks on and anterior to the pectoral collar are on the edges 
of the feathers, not the centres. 
I find considerable differences in sizein different specimens of this bird. Thus, No. 8456, 
from San Francisco, measures nearly 14 inches; the wing, 5.25; the tail, 6.40. No. 8455, 
(male,) from Tejon Pass, on the contrary, measures 10.40 inches; the wing, 4.65; the tail, 
5.50. The more southern specimens are smaller, and have the ashy brown of the back less 
glossed with blue. In most specimens the tail feathers are nearly truncate; in 2841, however, 
they are quite acute. 
In young birds the head is generally like the back, with only a faint shade of blue. There 
is a brownish pectoral collar, but no streaks of blue.

Hab .—Central line of Rocky mountains to table lands of Mexico. 
This species has so close a relationship to C. californica that it may not seem proper to separate 
them, but the differences are readily perceptible in large series. All of the Rocky mountain
