238 NORTH AMERICAN BIRDS. 



finer ; anal 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 toward the ends ; longest (fourth) with 

 six oblique transverse patches of slate, the outlines of which are much broken. Wing- 

 formula, 4, 5, 3-6-2 ; 1 == 10. Wing, 13.00 ; tail, 9.50 ; tarsus, 3.70, naked portion, 1.35 ; 

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



No. 8,508 (Fort Steilacoom, Puget Sound, Washmgton Territory ; Dr. Suckley. Var. 

 striatulm^ Ridgway). Similar to No. 44,940, but the upper surface more bluish, the shafts 

 of the feathers more conspicuously black ; the dorsal feathei'S nearly black around their 

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

 ash, sprinkled transversely with innumerable zigzag dots of white, these gradually in- 

 creasing in width posteriorly, where they take the form of irregular 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 black, these contrasting conspicuously 

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

 to their bases, the usual white spots being almost obsolete. Wing-formula, 4- 5, 3 - 6 - 

 2-7-8-9, 1. Wing, 12.50; tail, 9.10; tarsus, 2.60, the naked portion, 1.40; middle 

 toe, 1.75. 



Adult female (12,239, Brooklyn, N. Y. ; J. 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, corresponding witli 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, 1.60-1,20; middle toe, 1.95; inner, 1.40; outer, 1.45; pos- 

 terior, ] .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 upper surfiice; tail-bands appreciable, much broader than in 9? ^c*. 12,239, the sub- 

 terminal one being 1.61, the rest l.\i), wide, instead of 1.10 and .70. The longest upper 

 tail-coverts with narrow white tips; white sjiots on inner webs of primaries more dis- 

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

 formula, 4, 3, 5-6-2-7, 1 = 10. Wmg, 14.70; tail, 11.50; tarsus, 2.50; the naked 

 portion, 1.10 : middle toe, 2.00. 



Young male (second year. No. 20,920, Nova Scotia, June ; W. G. Winton). Plumage 

 very much variegated. Head above, nape, and anterior portion of the back, ochraceous- 

 white, each feather with a central stripe of lirownish-black, these becoming more tear- 

 shaped on the nape. Scapulars, back, wing^-coverts, rump, and upper tail-coverts umber- 

 brown ; the feathers 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 subterminal one separating the two 

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

 terminal crescentic bars. Tail cinereous-umber, with five conspicuous bands of blackish- 

 brown, the last of which is subterminal, and broader than the rest ; tip of tail like the 

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

 the edges by the white of the edge, which, frequently extending along the margin of the 

 black, crosses to the shaft, and is sometimes even apparent on the outer web ; the lateral 

 feather has the inner web almost entirely white, this, however, more or less finely mottled 

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

 bands also cross more obliquely than on the middle feathers. Secondaries grayish-brown, 

 with five indistinct, but quite apparent, dark bands ; primaries marked as in the adult, 

 but are much lighter. Beneath pure Avhite, all the feathers, including lower tail-coverts, 

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