parts dull reddish-brown, with the streakings but faintly indicated, and 

 scarcely any appreciable ashy either above or beneath. The first plumage 

 is worn by the young of this species for an unusually long time. 



68. Spizella socialis. 



First •plumage : male. Above light reddish-brown, lighter and with an 

 ashy tinge on the nape and rump, every feather streaked centrally with 

 dark brown. Superciliary line and a poorly defined median stripe upon 

 the crown pale fulvous. Beneath ashy-white, spotted and streaked every- 

 where, excepting on throat, anal region, and crissum, with dull black. 

 From a specimen in my collection shot at Cambridge, Mass., July 9, 1873. 



69. Spizella pusilla. 

 First plumage : male. Above olivaceous-ashy, the feathers of the inter- 

 scapular region with central streaks of dark brownish-chestnut. Crown, 

 occiput, and nape unmarked. Entire under parts, including sides of head, 

 light brownish-ashy, paler posteriorly. A broad band across the breast 

 of fine, faint, but distinct spots of reddish-brown. From a specimen in my 

 collection taken at Belmont, Mass., July 30, 1875. Young of this species 

 in first plumage are readily separable from those of <S. socialis by the plain 

 crown and finer spottings of the under parts. 



70. Zonotrichia albicollis. 



First plumage : male. Above bright reddish-brown, darkest upon the 

 crown, the feathers of the interscapular region with obscurely defined dark 

 brown centres. Superciliary stripe, and a poorly defined median stripe 

 upon the crown, brownish-white ; no decided yellow anterior to the 

 eye. Beneath brownish-white, with dusky streakings everywhere ex- 

 cepting upon the abdomen. From a specimen in my collection taken at 

 Upton, Me., July 30, 1874. 



71. Zonotrichia leucophrys. 



First plumage. Throat, breast, sides, and interscapular region streaked 

 thickly with dull black, most broadly so on the back ; on the throat these 

 streaks are reduced to mere spots ; lateral stripes of crown dark brown ; 

 central stripe dirty white. Anal and abdominal region immaculate. Cris- 

 sum faintly spotted. Otherwise like adult. From specimen in the col- 

 lection of J. Murdoch, obtained by him at Labrador, July, 1876. 



72. Chondestes grammica. 



First plumage. Crown dark brown, faintly tinged with chestnut. A 

 median and two lateral stripes of pale brownish-yellow. Best of upper 

 parts similar to the adult, but with the rump obscurely spotted, and the 

 streaking on the feathers of the interscapular region much broader. Lores
