 it is said to be numerous, but in Argentina only occurs on the northern 

 and eastern frontiers (in Tucuman and Misiones), where it frequents 

 the forests. 



366. PENELOPE OBSCURA, Temm. 

 (DARK GUAN.) 



Penelope obscura, Scl. et Salv. Nomencl p. 136; iid. P. Z. 8. 1870, p. 525; 

 Barrows, Auk, 1884, p. 275 (Entrerios). Penelope bcliviana, Burm. 

 P. Z. S. 1871, p. 701 (Tucuman) ? Penelope pileata, White, P. Z. S. 1882, 

 p. 627 (Catamarca) ? 



Description. Dark bronzy green ; lower back and abdomen chocolate-brown ; 

 feathers of upper back, wing-coverts, and body beneath down to the middle of 

 the belly margined with white ; feathers of front part of head edged with silvery 

 white: whole length 25*0 inches, wing 11'5, tail 12-0. Female similar. 



Hab. Paraguay, Northern Argentina, and Bolivia. 



This Guan was first made known to us as an inhabitant of Paraguay 

 by Azara, who described it in his ' Apuntamientos ' * under the name of 

 " El Yaciihu " or " Pavo del Monte" (Wood-Turkey) of the Spaniards. 

 The examination of skins of it obtained by Capt. J. T. Page, of the U.S. 

 Navy, during his expedition up the Rio Paraguay and Rio Vermejo, 

 enabled Messrs. Salvin and Sclater to make this identification. 



In Entrerios, Mr. Barrows tells us, this species is limited to the 

 borders and islands of the River Uruguay, where in heavy growths of 

 timber it is not uncommon, though rarely seen. Here it builds a large 

 nest in the trees and lays white eggs. 



It is probable that the Guan of Tucuman called by Dr. Burmeister 

 Penelope boliviano, and that of Catamarca referred by White to 

 P. pileata likewise belong to this species.
