Xiphocolaptes ignotus, sp. nov. 



Sp. Chae. — Similar to X. virgdtus, but much more rufesceut, streaks 

 on pileum and hind-neck much narrower, those on breast, etc., much less 

 regular, throat whiter, belly less distinctly spotted, and under tail-coverts 

 barred with dusky. 



Hae. — Ecuador. 



Young male (type, No. 52G3, Am. Mus. Nat. Hist,, Ecuador; Verreaux 

 collection, No. 38684). — Pileum, hind-neck, back, and scapulars mummy- 

 brown, the first two narrowly streaked with light brownish or tawny 

 buff, tbe upper back with a few narrow shaft-lines of the same; wings 

 (including lesser and middle coverts), lower back, rump, upper tail-cov- 

 erts, and tail, deep cinnamon-rufous or hazel, tbe outer webs of greater 

 wing-coverts, primary coverts, and primaries more like the color of the' 

 back, and terminal portion of inner webs of six outer primaries dull 

 dusky brown. Sides of head streaked with light buff and deep brown, 

 the latter prevailing on upper portion of auricular region, the former 

 predominating elsewhere; the two colors in about equal amount on 

 malar region. Chin and upper throat plain dull white; rest of under 

 parts light tawny-brown, the chest, breast, and sides broadly streaked 

 with pale buff, each streak margined laterally with a blackish line; 

 middle of lower breast with similar but more irregular streaks, with the 

 blackish margin broken into spots, the belly similarly marked, but the 

 paler streaks less defined and the general color more tawny; under 

 tail-coverts broadly barred with blackish, the bars interrupted, how- 

 ever, by a narrow pale tawny streak along the shaft of each feather. 

 Bill horn-color, becoming brownish white at tip; legs and feet dusky 

 horn color. Length (mounted specimen), about 10.00; wing, 5.75; tail, 

 4.80; culmeu, 1.87; depth of bill at gonydeal angle, .40; tarsus, 1.25; 

 middle toe, 1.12. 



The specimen described is undoubtedly a young bird, though fully 

 grown, except perhaps as to the bill. The adult would doubtless be 

 somewhat different in plumage, but, judging from other species, could 

 not be so much different as to render its identity with any other species 

 with which it has been compared at all likely.
