102 REVIEW OF AMERICAN BIRDS. [PART I. 
nearly equal zones of each color from nape to end of tail coverts ; more obscure 
posteriorly, and the white changing rather to light brownish-ash. Wings 
blackish, with about five series of brownish-white spots extending over outer 
webs; quills edged internally (not spotted) with the same. Tail feathers 
black, with about seven transverse light bands, narrower than their inter- 
spaces ; whitish on the outer webs and ed_es of the inner ; sometimes obscured 
and irregular medially ; most distinctly transverse on the lateral feathers, and 
most obsolete on the inner webs of the central feathers. Beneath whitish ; 
chin immaculate; throat and jugulum first with large rounded, then cordate, 
light-brown spots, which, on the breast, become transverse bands or zones 
covering the remaining under parts to end of crissum; more obsolete, with the 
ground color soiled with brownish, on the middle of the belly: these bands 
quite similar in 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 Ist primary, 1.30, of 2d, 2.30, of longest, 4th (measured from ex- 
posed base of lst primary), 2.65; 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 very similar in markings and coloration of the 
upper parts to C@. zonatus; the principal difference 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 instead of pale 
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. (. zonatoides also lacks 
the longitudinal streaking of blackish and white on the nape seen in 
pallescens, megalopterus, and zonatus. 
In the museum of the Philadelphia Academy I find specimens of 
a Campylorhynehus, labelled “ Picolaptes megalopterus, Latfr., 
Amerique Meérid.,” which agree perfectly with Lafresnaye’s descrip- 
tion, aud are those referred to by Dr. Sclater, in his paper published 
in Proceedings Phila. Academy, 1856, 264. 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 oeciput) ; the nape similar, the.central
