crencont, while streaked wiUi blue ; bcliind it dull wliilo ; the eidca tinged willi brown. Lenglli, 12.25 ; wing, f) ; tail, C. 15 ; 

 tarsus, 1.55. (2841.) 



Hall. — I'acific coast from Columbia r:ver south. Not in the interior. 



The forehead anil 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. Tiiere 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 ditlerences in size in 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.
