REVIEW OF AMERICAN BIRDS. 



[part I. 



nearly eciual zones of each color from nape to end of tail coverts ; more obscure 

 posteriorly, and the white changing rather to ligl brownish-ash. Wings 

 blackish, with about five series of brownish- white sjots exten ling over outer 

 webs ; quills edged iuternally (not sp()ttK<l) with the same. Tail feathers 

 black, with about sevnu transverse light bands, narrower than their inter- 

 spaces ; whitish on the outer webs and ed.ee of th' innei ; sometimes obscured 

 and irregular medially ; most distinctly transverse on the lateral feathers, and 

 most objolete on the inner webs of th<,* central " others. Beneath whitish ; 

 cuin immaculate ; throat and jugulum first with te rounded, then cordate, 

 light-brown spots, which, on the breast, become liu.sverse bands or zones 

 covering the remaining under parts to end of crissum ; more obsolete, with the 

 ground coloi' soiled with brownish, on the middle of the belly . these bands 

 quite similar iu size and proportion to those on the back, A white band from 

 bill over the eye to nape, with a brown one behind the eye ; sides of head 

 finely streaked with brownish. 



(13,659.) Total length, 7.00 ; wing, 3.50 ; tail, 3.40 ; graduation, .60 ; exposed 

 portion of 1st primary, 1.30, of 2d, 2.30, of longest, 4th (measured from ex- 

 posed base of Ist primary), 2.()5 ; length of bill from forehead, .85, from 

 nostril, .53; along gape, 1.00; tarsus, 1.00; middle toe and claw, .82; claw 

 alone, .27 ; hind toe and claw, .80 ; claw alone, 37. 



This species is veiy similar in markings and coloration of the 

 upper parts to C. zonatus ; the principal diftcreuce being in the 

 absence of the rufous tinge of the rump, a more distinctly banded 

 tail, and the inner edges of the quills being continuously edged with 

 brownish-white, not spotted with reddish-white. Beneath the differ- 

 ence is very strongly marked, in the continuous transverse bands on 

 the body : the absence of the reddish color of belly, flanks, and 

 crissum, etc. : the longer wings, and other peculiarities of proportion. 



To C. zonatoides, of Bogota, the resemblance above is almost per- 

 fect, and beneath it is quite close ; the spots of black inste.rd of r)ale 

 brown, absence of zones on flanks and crissum (although the spots 

 are transversely elongated), and the rufescence of the posterior region 

 of body will, however, distinguish them. G. zonatoides also lacks 

 the longitudinal streaking of blackish and white on the nape seen in 

 palleacens, megalopterns, and zonatus. 



In the museum of the Philadelphia Academy I find specimens of 

 a Campylorhynchus, labelled " Picolapies megalopterus, Lafr., 

 Amerique Mcrid.," which agree perfectly with Lafre.snaye's descrip- 

 tion, and are those referred to by Dr. Sclater, in his paper published 

 in Proceedings Phila. Academy, 1850, 204. These differ very 

 appreciably from the present species in having the light bands above 

 of a purer white and more sharply defined, the feathers of the hood 

 dark-brown, conspicuously streaked centrally with grayish-white 

 (with a reddish tinge on the occiput) ; the nape similar, the central
