238 NOUTII AMERICAN UIRDS. 



finer; iinal region finely barred; lower tail-coverts immaculate pure white. Lining of the 

 wing barred more coarsely and irregularly than the breast ; under surface of primaries 

 with white prevailing, this growing more silvery towanl the ends ; long(,'st (fourth) with 

 six oblique transverse patches of slate, the outlines of which are nuicli liroken. Wing- 

 foi inula. 1, ."). ;;-(i-2; 1=10. Wing, KJ.Od ; tail, !t.50; tarsus, 3.7t', naked portion, 1.3J; 

 middle toe, 2.00 ; inner, 1.21; outer, 1.37; posterior, 1.00. 



Xo. 8,'}0S (Fort Steilaeoom, Puget Sound, Washington Territory ; Dr. Suckley. Var, 

 slriatiihix, Hidgway). Similar to Xo. 44,9-10, luit the upper surface more bluish, the shafts 

 of the feathers more conspicuously black ; the dorsal feathers nearly lilack ar(jund their 

 borders. Tail-bands nearly obsolete. Lower parts with the ground-color fme bluish- 

 ash, sprinkled trausver.sely with innumerable zigzag dots of white, these gradually in- 

 creasing in width posteriorly, where they take the Ibrm of irregidar transverse bars: 

 crissum sparsely and coarsely sprinkled with slaty. Each feather of the lower parts with 

 a very sharply defined narrow shaft-stripe of deep lilack, the.se contrasting conspicuously 

 with the bluish, finely marked ground-color. Under surface of primaries uniform slaty 

 to their bases, the usual white spots being almost obsolete. Wing-fornuda, 4 - o, 3 - G - 

 2-7-8-9, 1. Wing, 12.50; tail, 9.10; tarsus, 2.G0, the naked portion, 1.40; niidd'o 

 toe, 1.75. 



Adult femitle (12,230, Brooklyn, N. Y. ; .7. Ackhurst). Almost precisely similar to the 

 male. Slate above less bluish; bands on tail more distinct, five dark ones (about .75 of an 

 inch in width) across the brownish-slate ; obscure light bands indicated on outer webs of 

 primaries, corresjionding with those on inner webs; lores more grayish than in male; 

 bars beneath more regular ; longitudinal streaks blacker and more sharply defined. Wing, 

 14.25; tail, 11.25; tarsus, l.CO-1,20; middle toe, 1.95; inner, 1.40; outer, 1.45; pos- 

 terior, 1.30. 



No. 59,892, (Colorado ; F. V. Hayden, var. striatulus, Ridgway), Similar to male No. 

 8,508, described above, but differing as follows: interscapulars uniform with the rest of 

 the upi)er surface; tail-bands appreciable, much broader than in 9, Xo. 12,239, the sub- 

 terminal one being l.Gl, the rest 1.10, wide, instead of 1.10 and .70. The longest upper 

 tail-coverts witii narrow white tips; white spots on inner webs of primaries more dis- 

 tinct. Black shaft-streaks on lower surface broader and more conspicuous. Wing- 

 fonuula, 4, 3, 5-G-2-7, 1 = 10. Wing, 14.70; tail, 11.50; tarsus, 2.50; the naked 

 portion, 1.10 : middle toe, 2.00. 



Youiiij male (second year, Xo. 2G,920, Nova Scotia, .June ; W. G. Winton). Plumage 

 ver}' much vaiiegated. Head above, nape, and anterior portion of the back, ochracoous- 

 white, each feather with a centr.il stripe of l)rownish-black, these becoming more tear- 

 sliaped on the nape. Scapulars, back, wing-coverts, rump, and upper tail-coverts umlier- 

 brown : the fcatliers with lighter edges, and with large, more or less concealed spots of 

 white, — these are largest on the .scapulars, where they occupy the basal and middle thirds 

 of the feathers, a band of brown narrower than the sul)terininal one separating the two 

 areas ; ujiper tail-coverts similarly marked, but white edges broader, forming conspicuous 

 terminal crcscentic bars. Tail cinereous-umber, with five conspicuous ban<ls of blackish- 

 bruwn, iIm! last of which is subtermin.il, and broader tiian the rest; tip of tail likj the 

 pale bands; the bauds are most sharply defined on the inner webs, being followed along 

 the eilges by the white of the edge, which, fretpiently exteniling along the margin of the 

 black, crosses to the .sliaO, an<l is sometimes even apparent on the outer web ; the lateral 

 featlier has the inner web .ilmost entirely white, this, however, more or less finely mottled 

 with giayish, the mottling becoming more dense toward the end of the feather ; the 

 bands ;dso cross more obti(|uely than on the middle fi-athers. Sei'ondaries grayish-brown, 

 with five indistinct, but (piite a|)parent, dark bands ; primaries marked as in tlie adult, 

 but are nuich lighter. Beneath ])ure white, all the fi'athers, including lower tail-coverts, 

 with sharp, central, longitudinal streaks of clear dark-brown, the .shafts of the feathers
