Wing, 18.25-23.70 ; tail, 8.70-13.00 ; culmen, 1.20-1.60 ; tarsus, 3.25- 

 4.30; middle toe, 2.40-3.30. Adult: — General color deep black, the 

 lower parts posterior to the breast (including lining of tlie wing) pure 

 white, and the lesser and middle wing-coverts ash-gray ; the white and 

 ashy portions narrowly and closely barred with dusky slate or black- 

 ish; chin, throat, and cheeks pale grayish with black shaft- streaks; 

 feathers of the neck and breast, also the uj)per tail-coverts and the 

 rectrices, sometimes minutely tipped with white or grayish. Yoimg : — 

 Above chiefly black, the wing-coverts barred with grayish and ochra- 

 ceous-white (in older specimens), or irregularly mottled with black and 

 ochraceous (in younger individuals). Head streaked with black and 

 ochraceous-white, lower parts mixed black and ochraceous, the relative 

 amount of the two colors, and the depth of the ochraceous tint varying 

 with the individual, but the ochraceous usually predominating poste- 

 riorly, the former being mostly in large suffused spots, chiefly on the 

 breast and sides. Tibite usually immaculate, but sometimes narrowly 

 barred with blackish. 



Mr. Sharpe describes the tail of the "young male" as "ashy gray, 

 mottled with black, more distinctly toward the apex, which is entirely 

 black"; but we have seen no specimens in which the tail is not entirely 

 black, even to the extreme base, except a narrow grayish terminal mar- 

 gin, present in most specimens. A young specimen from Brazil (Ko. 

 50,929, Sr. Don Fred. Albuquerque) is nearly uniform black beneath 

 as far back as the tibi?e and crissum, which are deep yellowish ochrace- 

 ous, with irregular black bars on the former, and zigzag spots of the 

 same on the latter. In this specimen, the wing-coverts are pale gray, 

 nearly white anteriorly, everywhere barred with dusky, with but little 

 admixture of ochraceous; the pileum aud nape are also nearly uniform 

 black, nearly all the white or ochraceous being beneath the surface. 



An adult from Bogota (No. 66,323) differs from Chilian examples of 

 the same stage in having a glaucous or chalky cast to the black por- 

 tions of the lilumage, especially on the head, neck, back, and jugulum ; 

 the slaty bars of the abdomen, etc., are also narrower and fainter, those 

 of the crissum being much broader and darker than elsewhere. 



The tail and upper coverts are more often tipped with grayish than 

 with white. 



In an adult specimen, the bill was "black at the tip, j-ellowish-green 

 at the base; eye light hazel; legs and toes chrome-yellow; claws 

 black. Total length, 18 J inches."— (Scl. & Sal v. P. Z. S. 1869, p. 155.)
