Sp. Cb. — Above dull grayish olive green. Crown uniform chestnut. Forehead with superciliary stripe, and sides of the 

 head and neck, the upper part of the breast and sidea of the body, bluish ash. Chin and upper part of throat abruptly defined 

 white, the former margined by dusky, above which is a short white maxillary stripe. Under tail coverts and sides of body 

 behind brownish yellow. Tail feathers generally, and exterior of wings bright olive green, the edge and under surface of the 

 latter bright yellow ; edge of first primary white. Length, about 7 inches ; wing, 3.20 ; tail, 3.65. 



Hab. ^Valley of Rio Grande and Gila ; Rocky mountains north to the South Pass ; south to Mexieo. 



In this species the wing is consideraUy rounded, tlie tertials considerably shorter than the 

 primaries, and not exceeding the secondaries ; the fourth quill longest, the first shorter than 

 the sixth, the second and fifth quills considerably longer than the rest. The tail is long and 

 considerably graduated, the outer feather half an inch shortest ; the feathers broad and obtusely 

 pointed, the corners rounded. 



The extent of the chestnut of the crown varies somewhat ; more extended probably in the 

 males. The region on the side of the head, adjoining the nostrils, is whitish ; the small feathers 

 under the eye are spotted with the same. The posterior outline of the ash of the breast is much 

 less sliarply defined than the anterior. 



Specimens vary in the brightness of the olive above, which is never as pure as that of the 

 wings and tail. The olive of the tail, too, is darker than that of the wings. 



A very young bird (1896) has the whole under parts dull white, streaked and spotted on the 

 sides of the throat, and on the breast, with dark brown. The crown and back are also thickly 

 spotted. In 5734 the ash of the breast has made its appearance ; the middle of the belly is 

 white, spotted ; the chin white, encircled by spots. The spots above are restricted to near the 

 head, and there is a small central patch of chestnut on the crown. 



No. 1896 is the original green-tailed spscrrow killed July 12, 1834, by Towrisend, and described
