on each side the tliroat from the chin to the sides of the neck, where it runs into a close patch of black streaks continued along 

 the breast and sides to the root of the tail. Outer two tail feathers with an oblique patch on the inner web near the end ; the 

 others edged internally with white. Female similar, except that the upper parts are olivaceous and, even on the crown, streaked 

 with black ; the white on the sides and across the breast tinged with yellowish ; a ring of the same round the eye cut by a dusky 

 line through it. Length of male, 5.75 ; wing, 3 ; tail, 2.25. 



Hab. — Eastern North America to the Missouri high plains. Cuba, (Gundlach.) Greenland, (Reinhardt.) 



The wings are long and pointed ; the second longest ; the first a little longer than the third. 

 The tail is slightly emarginate and scircely rounded. The size of sjJecimens varies considerably ; 

 thus, in one (4645) the wing measures .40 of an inch more than the type selected^ (1545.) 

 Specimens generally from the Mississippi valley appear larger than more eastern ones. 



Tlie young birds in the autumnal dress are very different from the spring. The upper parts 

 are light olive green, obsoletely streaked with brown ; beneath greenish yellow, obsoletely 

 streaked on the breast and sides, the under tail coverts pure white, a yellowish ring round the 

 eye, and a superciliary one of the same color. In this dress it is scarcely possible to distinguish 

 it from the immature D. castanea. The differences as far as tangible will be found detailed 

 under the head of the latter species.
