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.

 comayo.) 



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.

Oberholser ^° has indicated that Gliloronerpes Swainson, 1837, is 

 to be replaced by Picidus Spix, 1824. 



The present species was encountered in the Chaco on only a few 

 occasions in heavy woods in the vicinity of streams. Two males
