168 NORTH AMERICAN BIRDS. 



B. Tail tipped with deep rufous; outer tail-feather unvariegated. 



5. Head above dark slaty-plumbeous, without any rufous. ^. Tail 

 continuous rufous to the extreme tip, the subterminal black band 

 narrower than the terminal rufous one, and not continuous ; the outer 

 feather entirely rufous, without any black. In other respects much 

 like var. ausiralis. ( 9 not seen.) Hah. Chile and Western Brazil.

markings linear only on the breast, becoming tear-shaped and circular on the sides, and trans- 

 verse on tlie flanks ; the red patch on the crown is (|uite extensive. In the whole series the third 

 quill is longest, and the bill is, in all, considerably longer than in any specimen of sjMrverius ex- 

 cepting those from Florida. Another female from St. Thomas (36,551 ; Robert Swift) is almost 

 exactly like the one from Porto Rico ; the rufous of the crown covers nearly the whole top of the 

 head, and is quite bright. In a series of skins belonging to Mr. Newton, deposited in the S. I. 

 Collection, we hud a pair of this variety from the island of St. Croix, W. I. They are perfectly 

 typical examples. The male (" May 2, 1857, B. B.") has the large black spots of the side trans- 

 versely cordate ; the bands on the tail are broken into spots on edges of the feathers ; the female 

 ("s. p. 227, B. 6 ") is in nearly all respects like the specimen described.

Hah. Chile and Western Brazil. 



Adult $ (48,821, Valdivia, Chile, January, 1864; Nat. Mus. of Chile, Dr. Philippi, Dir.). 

 Somewhat like var. australis ; in fact, resembling this in general appearance. Head above, how- 

 ever, very dark dull plumbeous, with very distinct shaft-streaks of black. Back and scapulars 

 sparsely barred with black, the bars broadest posteriorly. Tail much brighter rufous than the 

 back ; continuous rufous to the extreme tip ; a very narrow subterminal band of black, .30 of an 

 inch wide, crossing about .55 of an inch from the tip, making the terminal deep rufous, nearly 

 twice as w'ide as the black ; toward the outer feathers the black is thrown into a spot on each 

 web, scarcely touching the shaft ; on the lateral feather the black is lacking entirely, the inner 

 web being continuous rufous, the outer paler, inclining to ochraceous-white. Primaries con- 

 spicuously white terminally ; inner webs white, with transverse bars of dusky ; there being on 

 the longest (second) ten spaces of wdiite, these more than twice the width of the dusky bars ; 

 lining of the wing creamy-white, with minute streaks of black sparsely distributed. Forehead 

 more hoary than the crown ; lores white. Ear-coverts, neck, and entire lower parts, continuous 

 dull white ; breast with a few minute black streaks ; flanks with more expanded tear-shaped 

 dashes of the same. The "mustache" is very conspicuous, as are also the oral, cervical, and 

 nuchal markings. Wing-formula, 2 = 3-1, 4. Wing, 7.40; tail, 5.15; tarsus, 1.40; middle 

 toe, .95 ; culmen, .50. No. 50,944 (Brazil ; Sr. Don Fred. Albuquerque) is exactly similar.
