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

 June 8, 1874. 



8. Re§ulua ^atrapa. 



First pluinage: female. Pileum (including forehead) dark amoky- 

 brown ; line over the eye entirely cut off at its anterior comer by the june^ 

 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 -vyay 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 broaklens to meet its external 

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

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

 is produced I^st 



9. Folioptila caerulea. 



First phmrmge : male (J). Rectrices as in the adult ; i-emiges 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., West Va., June, 1872. 



10. Lophopbanes bicolor. 



First plumage: male. A-bove dull ashy, frmital 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. Farus atricapillus. 



F'ir^t plfjfmiMge: male. Back very dark slate without any tinge of 

 brownish. Beneath salmon-color, f^test 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. 



From about the timfi of pairingan spring till early autumn this Tit- 

 mouse wears a plumage which has been almost, if not entirely, ignored by 

 writers. The back is clear ashy without any brownish or olivaceous 

 washing except in a fejv specimens on the rump. The under parts are 

 white, with barely a tr i I'e of faintest salmon on the sides, of the body ; whUe 

 the white margining uj. the. remiges is much narrow:ed and on many of 

 the feathers replaced by ashy. It may be objected that this generally- 

 paler condition is due to the wearing of the feathers consequent upon the 

 continual ^passing of the birds in and out of their nesting cavities, but not 

 all of the specimens before me are iv, worn pluinage ; one pair, taken May 

 12, 1876, being in remarkably perfect dress. At all events, whatever the
