XIPHORHYNCHUS PUNCTIGULUS PUNCTIGULUS (Ridgway). 
SPOTTED-THROATED WOODHEWER. 
Somewhat like X. erythropygius, but color of pileum, back, and 
under parts greenish or ocherous olive instead of olive-brown, back 
without streaks or with very narrow ones on anterior portion only, 
and throat spotted rather than barred with dusky. 
Adults (sexes alike).—Pileum deep olive, the feathers more or less 
broadly tipped or terminally margined with dusky, and usually (some 
of them at least) with a narrow shaft-streak of pale buff; hindneck, 
back, and scapulars deep ocherous olive, the more anterior scapulars 
and interscapulars sometimes with a very narrow mesial streak of 
light buff; rump, upper tail-coverts, and tail chestnut, the shafts of 
rectrices darker; wing-coverts and most of outer webs of primaries 
olive, the secondaries chestnut, but outer webs of distal ones edged 
with olive; an indistinct superciliary stripe of light buff (obsolete 
anterior to eye) broken by dusky olive margins or edgings to the 
feathers; lores nearly uniform dusky; auricular region streaked with 
dusky olive and light buff or yellowish buff, the suborbital and 
malar regions dusky olive spotted or speckled with buffy; chin and 
throat buff, the latter with a triangular or diamond-shaped spot of 
deep olive on tip of each feather; rest of under parts clear, somewhat 
greenish, olive, each feather with a central cuneate, guttate or fusi- 
form spot of buff, these markings narrower (streak-like) on sides, less 
distinct on flanks; under tail-coverts buff mesially (broadly), edged 
with olive, the longer ones nearly uniform rusty; under wing-coverts
