light cinnamon, tinged with rusty, streaked with pale buffy, the middle 

 of the belly barred with brownish ; sides, tlanks, under tail coverts, and 

 under wing-coverts nearly uniform cinnamon-rufous or rusty. Bill horn- 

 colored basally, horn-whitish on terminal half; legs and feet dusky.* 

 Length (skin), 12.00; wing, 5.80; tail, 4.50; culmen, 2.32; tarsus, 1.30; 

 middle toe, 1.07. 



The type of Dendrocolcuptes rubiginosus Lafr., now before me, agrees 

 closely in coloration with the specimen described above, and undoubt- 

 edly belongs to the same species. It has the chin and throat a little 

 paler, however, and the ear-coverts less distinctly chestnut, and the bill 

 almost wholly horn-whitish. Length (mounted specimen), 11.50; wing, 

 6.00 ; tail, 4.80 ; culmen, 2.52 ; depth of bill at angle, .42; tarsus, 1.40 ; 

 middle toe, 1.12. 



Speaking of specimeus from Lainbarti, Paraguay, Count von Berlepsch 

 remarks as follows (J. f. O., 1887, 15) : 



The female collected on the 8th of January has blackish edges on the tips of the 

 feathers of the crown, of which markings the other female shows no trace. The 

 other has conspicuously red-brown cheeks [auriculars] and seems to be an older, 

 more highly-colored bird. This bird also agrees essentially with a specimen in my 

 collection from Tucumau. 



It should be noted that in Vieillot's description of this species is an 

 important error, in the statement that the under parts are streaked with 

 black, whereas they are streaked with whitish. Since Vieillot expressly 

 says that all the other species of the genus are streaked with wliite, it 

 would seem that the mistake is not a mere u slip of the pen," thus ren- 

 dering it probable that Azara himself, inadvertently perhaps, commit- 

 ted the error. 



Xiphocolaptes major castaneus, subsp. uov. 



Xiplwcolaptes major Scl., Cat. Am. B., 1861, 164 (Bolivia; nee DendrocoJapte* major 

 Vieill.).— Scl. & Salv., Ex. Orn., pt. v, Jan., 1868, 71 (excl. syn.), pi. 36 

 (Bolivia). — Scl. & Hudsox, Arg. Orn., i, 1888, 201, part (description). 



Sp. Char. — Similar to A", major (Vieill.) of Paraguay and Argentina, 

 but much deeper colored, especially on the head, neck, and under parts, 

 the chin and throat dull russet- brown, instead of cinnamou-buffy, the 

 light streaks of breast, etc., much narrower, bars on belly obsolete, and 

 under tail-coverts deep chestuut. 



Hab. — Bolivia. 



Adult female (type, No. 33648, Am. Mus. Nat. Hist., Piedra Blanca, 

 Bolivia, April 20,1886; H. H. Smith). — Head russet-brown (scarcely 

 paler on chin and throat), the ear-coverts chestnut, and the lores dusky; 

 hind-neck chestnut-russet, deepening into bright rufous chestnut on 

 other upper parts, the upper tail-coverts being deep chestnut and the tail 

 dark chestnut, with dusky shafts ; feathers of pileum, hind-neck, upper 

 back, chin, and throat with very narrow and indistinct paler shaft streaks. 

 Color of the under parts gradually brightening from brownish russet 



* "Iris light brown; beak pale slate, tip darker ; legs and feet olive-green." (DURN- 

 ford, Ibis, 1880, 359.)
