REVIEW OF AMEKICAN BIRDS. 



[part I. 



Anlhus rufescens, D'Oeb. & Lafk. Mag. Zool. 183G.— D'Okb. Voyage, 

 226 (Bolivia). Not rufescens of Temminck. 



(30,912, Quito.) Plumage very dense and full on the under parts ; wings 

 broad, their point formed by the outer five primaries, of which the 4th is 

 longest ; then 3d, and 5th equal 2d, little shorter ; the first .14 shorter than 

 the 5th, and ,20 longer than 6th, about equal to the longest secondary. Tail 

 moderately forked, rather shorter than the wings. Hind claw quite consider- 

 ably curved, and short, about equal to its digit. 



Feathers of upper parts light brownish-yellow, streaked centrally and con- 

 spicuously with dark-brown ; scarcely appreciable on the wing coverts, which 

 are more rufous. Ocular regions with under parts pale buff, lighter posteriorly 

 and on chin and lores ; darker on the inside of the wings. Sides of neck streaked 

 with dark-brown, and a series of scarcely appreciable dusky spots in the tips 

 of the feathers across jugulum, very few in number (scarcely more than one 

 row). Quills broadly edged internally with dull cinnamon. Outer tail feathers 

 rufous, or brownish-white at tip and for about exterior half, including the 

 region both sides the shaft ; second feather with slight streaks of the same 

 along the end of the shaft ; other feathers dark-brown, edged like the back. 

 Bill brown, whitish at base below. Legs flesh color. 



A second specimen (35,035) agrees much better with Dr. Sclater's descrip- 

 tion, in being paler on the belly and crissum ; darker above ; the hind claw 

 longer (.55). The wing formula differs in being 2, 3, 1, 4, 5, and the 6th quill 

 is exactly midway from the 5th and 7th (.17 of an inch). 



Total length, 5.75 ; wing, 3.35 ; tail, 2.90 ; length of bill from forehead, 

 .62, from nostril, .37 ; along gape, .80 ; tarsus, .90 ; middle toe and claw, .83 ; 

 hind toe and claw, .75 ; claw alone, .40. 



Anthus . 



(21,035, % , Uruguay.) Wings not much longer than the tail ; the rounded 

 point formed by five outer primaries ; wing formula 3.4=2, 1, 5, the latter 

 which is one-fourth the distance from 4th to 6th. Inner secondaries rather 

 shorter than the 6th quill. Feet much as in Neocorys ; the hind claw nearly 

 straight, rather longer than its digit. 



All feathers of upper parts blaokish-brown, conspicuously margined on each 

 side (but not at tips) with brownish-yellow, which becomes grayish towards 

 the ends (except perhaps on the lower back) ; these margins proportionally 

 widest on the hind neck. Under parts soiled white, with a pale brownish or 

 buff (not yellow) tinge ; palest on throat, crissum, and middle of belly, deepest 

 on inside of wing and inner margin of quills ; the feathers of jugulum, upper 

 breast, and sides of body with conspicuous shaft streaks of blackish-brown ■ 

 feathers on the sides tinged throughout with pale brownish. Loral, ocular
