REVIEW OF AMERICAN BIRDS. 



[part I. 



Troglodytes brunneicollis. 



Troglodytes brunneicollig, Sclater, P. Z. IS. 1858, 297 (Parada ; Oaxaca). 



Hab. 



—la. Catal. 1861, 23, no. 150. 

 Southern Mexico. 



Bill short, compressed, and straight. First primary more than half longest. 

 Upper parts reddish-brown, brigliter on the ruiup. The back, rump, and 

 wings barred rather distinctly with dusky. The dark bars exhibit a ten- 

 dency to be succeeded by another bar lighter than the ground color, on the 

 ticapulars almost white. Greater wing coverts with a spot of whitish in the 

 end. Beneath, from chin to breast, brownish-buflF; middle of belly dull white, 

 with scant spots of brown. Lower part of sides and crissum tinged with 

 dark-brown, banded with suffused whitish and dusky — the dark hars, as on 

 the scapulars, being succeeded by a whitish bar lighter than the ground color. 

 Inside of wings similarly banded. Tail feathers reddish-brown, with zig-zag 

 narrow bars of black ; innermost (superior) secondary quills with contour lines 

 of dusky, instead of transverse bars. 



(29,709, %.) Total length, 4.40; wing, 1.90; tail, 1.85; graduation, .45; 

 exposed portion of Ist primary, .83, of 2d, 1.26, of longest (measured from 

 exposed base of Ist primary), 1.45 ; length of bill from forehead, .60, from 

 nostril, .35, along gape, .69 ; tarsus, .70 ; middle toe and claw, .71 ; hind toe 

 and claw, .59 ; claw alone, .27. 



This species somewhat resembles T. hyemalis, from which, how- 

 ever, its larger size, much longer tail, and browner breast distinguish 

 it. In none of its allies do we find the bands on the under side of 

 the wings, the whitish bars on the scapulars, and the general ten- 

 dency to have the dark bars succeeded by a whitish one. The legs 

 are unusually stout, the middle toe lengthened, and the Ist primary 

 longer than in any others, except inquietus.
