7. Sialia sialis. 



First plumage: female. Above dull smoky-brown, unmarked on head 

 and rump, the latter slightly paler ; but marked over the interscapular 

 region and wing-coverts by tear-shaped spots of white and pale fawn- 

 color, these spots occupying the central portions of the feathers. Second- 

 aries and tertiaries edged, and tipped with reddish-brown ; first primary 

 and lateral pair of rectrices with the outer webs pure white ; inner 

 primaries as in adult, but with the blue of a much lighter shade ; 

 posterior margin of eye with a crescentic spot of soiled white. Under parts, 

 with the exception of the abdominal region, which is nearly immaculate, 

 pale ashy-white, each feather broadly margined with dull cinnamon- 

 brown. From a specimen in my collection, shot at Cambridge, Mass., 



June 8, 1874. 



8. Regulus satrapa. 



First pluviage : female. Pileum (including forehead) dark .smoky- 

 brown ; line over the eye entirely cut off at its anterior corner by the junc- 

 tion of the dusky lores with the brown of the forehead ; tertiaries broadly 

 tipped with white ; breast strongly washed with pale fawn-color ; other- 

 wise like adult. From a specimen in my collection taken at Upton, 

 Me., August 25, 1874. A young male taken August 25, 1873, is in 

 every way similar. A good series of specimens of various ages shot 

 during August and the early part of September illustrate well the 

 transitional stages. First the brown of the pileum darkens into two 

 black stripes, while the line over the eye broadens to meet its external 

 margin. Next, two lines of yellow feathers appear inside and parallel 

 with the black ones, while the orange of the central space (of the male) 

 is produced last. 



9. Polioptila caerulea. 



First plumage : male (?). Rectrices as in the adult ; remiges paler, with 

 a much broader and whiter edging on the tertials ; rest of upper parts 

 pale mouse-color with a strong wash of light cinnamon. Entire under 

 parts grayish-white or pale lead-color. In my collection, from Kanawha 

 Co., WestVa., June, 1872. 



10. Lophophauea bicolor. 



First plumage : male. Above dull ashy, frontal hand scarcely darker ; 

 sides deep salmon-color. Otherwise like adult. From specimens in my 

 collection obtained by Mr. W. D. Scott at Coalburgh, West Va., July 20, 

 1872. 



11. Parus atricapillus. 



First plumage: male. Back very dark slate without any tinge of 

 brownish. Beneath salmon-color, faintest on breast, most pronounced on 

 sides and anal region. The black on throat and pileum scarcely less 

 clear than in adult. From specimen in my collection shot at Concord, 

 Mass., June 17, 1871.
