with dusky. Bill blackish, horn-color, feet grayish-black. Length 

 (skin), 10.50; wing, 5.G0 ; tail, 5.50 ; culuien, 1.80; depth of bill at gouy- 

 deal angle, .35 ; tarsus, 1.27 ; middle toe, 1.10. 



Three adults from Bogota in the collection of the American Museum 

 of Natural History (Lawrence collection) are essentially similar, but 

 have the streaks on lower parts broader and extending quite to the belly 

 and flanks, and indistinctly margined along each side with dusky; the 

 belly more heavily spotted with dusky or blackish ; two of them having 

 the under tail-coverts spotted. 



They measure as follows : 



This species may very readily be distinguished from its allies by the 

 very small, dark-colored bill (smaller than in any other member of the 

 genus), and from all except X. compressirostris Taczan., by the very 

 deep coloratiou, with distinctly spotted belly. All the skins examined 

 are of the well-known " Bogota " make. 



It is hardly possible to determine from the description (Rev. Zool., 

 1840, 270t) what species Lesson intended to describe under the name 

 Dendrocolaptes promeropirliyncUus, the uncertainty being rendered still 

 greater by the fact that he gave no locality. Lafresuaye, however, re- 

 described the species (Rev. et Mag. de Zool., 1850, pp. 09, 100), and 

 assigned to it the habitat "Colombia" ("satis frequeus"); and, pre- 

 suming that he had examined Lesson's type, I follow the general cus- 

 tom of identifying Lesson's name with the Bogota bird. 



Xiphocolaptes virgatus, sp. no v. 



Sp. Char. — Most like X. promeropirhynchus (Less.), but paler and 

 grayer on anterior upper parts, the back conspicuously streaked with 

 palebuffy; under parts much less tawny, with stripes broader; bill 

 stouter, light grayish horn-color, dusky only at base. 



Hab. — Unknown. 



Adult (type in Coll. Am. Mus. Nat. Hist, without number, local- 

 ity, or other data). — Pileum dull, dusky olive or olive-bistre, dis- 



* These measurements of total length are of course of little value, since they depend 

 wholly on the " make" of the skins. 



t " Bill, .05™ (or 25 lines long), very compressed, arched, black. Top of head dead 

 black, with an oblong spot of buff ("rouille") in the middle of each feather. 

 Neck above and back reddish-olive, with a rufous yellow lino in the middle of each 

 feather. Wings, rump, and tail cinnamon. Chin white; front and sides of neck, 

 thorax, and flanks yellowish-olive, with a longitudinal streak of yellowish-white 

 in the center of each feather. Middle of belly with three to four series of black 

 spots. Under [tail?] coverts rufous, spotted with black and with a light stripe in 

 the middle. Tarsi black. Total length, ,33 ra (12 inches)." (Translation.)
