bark from the dead limbs. The bill in this bird was pale smoke
gray, with the culmen lined with hair brown, the base of the mandi-
ble and the sides of the maxilla gray number 8; tarsus and toes
slate gray number 5
; iris dull Avhite.
This specimen differs from C. I. wvprocerus Bangs and Penard
in larger size, as the wing measures 193 mm., but is similar to a
male from Diamantina (near Santarem), Brazil, and to a series
from Surinam (in the Museum of Comparative Zoology) the near-
est approach to skins from the type-locality available.

Males of this fine species were secured at Las Palmas, Chaco, on
July 31, 1920, and near Kilometer 80, west of Puerto Pinasco, Para-
guay, on September 20. The species has been recorded previously
from the Rio Pilcomayo, Sapuca3% and Curuzu Chica, Paraguay,
and Pan de Azucar, Brazil, so that the first of these constitutes a
southward extension of range from information in published
records. The bird from Puerto Pinasco is distinctly browner in
tone than the one from Chaco. This species frequents the heaviest
growth of the swampy forests in the Chaco, where, save for its
persistent hammering as it chisels its food from decaying wood, it
might readily pass unnoticed. On careful approach through the
tangle of vines and thorny scrub the birds were found within a
short distance of the ground, often under such somber conditions
that even their light-colored, crested heads were hardly to be dis-
tinguished. In spite of Kerr's derogatory remarks regarding the
soiled appearance of his specimens, I found this a strikingly marked
and beautiful bird, the more so since its finely contrasted colors,
viewed amid its somber surroundings, came as a distinct surprise.
A fully adult male had the maxilla light mouse gray, becoming
dark quaker drab along the line of the culmen; mandible yellowish
glaucous, shaded at base with neutral gray; iris morocco red; tar-
sus storm gray; toes gray number 6.

The present species was encountered in the Chaco on only a few
occasions in heavy woods in the vicinity of streams. Two males
