No. 8,508 (Fort Steilacoom, Puget Sound, Washington Territory; Dr. Suckley. Var. _striatulus_, Ridgway). Similar to No. 44,940, but the upper surface more bluish, the shafts of the feathers more conspicuously black; the dorsal feathers 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 increasing 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 surface 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 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, 1.60–1.20; middle toe, 1.95; inner, 1.40; outer, 1.45; posterior, 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 upper surface; tail-bands appreciable, much broader than in ♀, No. 12,239, the subterminal one being 1.61, the rest 1.10, wide, instead of 1.10 and .70. The longest upper tail-coverts with narrow white tips; white spots on inner webs of primaries more distinct. Black shaft-streaks on lower surface broader and more conspicuous. Wing-formula, 4, 3, 5–6–2–7, 1=10. Wing, 14.70; tail, 11.50; tarsus, 2.50; the naked portion, 1.10; middle toe, 2.00.
