a catalogue of specimens with no description, but with a reference to 

 the iribu of Azara. On consulting Azara ^° it is found that the inhu 

 is the black vulture so that this name will antedate Vultur hrasilien- 

 sis Bonaparte." 



The type locality for the southern form, is thus Paraguay. Hell- 

 mayr ^- has held incorrectly that Vultur uruhu of Vieillot ^^ is a 

 synonym of Cathartes aura. Although in his discussion of the 

 species, Vieillot states that "un rouge sanguin colore la peau de la 

 tete et du cou " his diagnosis and plate can apply only to the black 

 vulture. In the general account of this species Vieillot points out 

 clearly the distinctions between the black and turkey vultures, and it 

 may be that his note on the color of the head and neck under the 

 black vulture refer to the purplish suffusion found on these parts in 

 the adult bird when recently killed. 



VULTUR GRYPHUS Linnaeus 



Vultur gnjphus Linnaeus, Syst. Nat., ed. 10, vol. 1, 1758, p. 86. (Chile.) 



On March 19, 1921, at El Salto, an estancia above Potrerillos, 

 Mendoza, at an elevation of 2,000 meters, I saw one of these birds 

 sailing above the valley. Tliree were observed above Uspallata, 

 Mendoza, on April 21. The male of this species is known as condor, 

 the female as huitre, a distinction that may lead to confusion as it 

 would indicate that two distinct species were intended.

MILVAGO CHIMANGO CHIMANGO (Vieillot) 



Polydorus chimango Vieillot, Nouv. Diet. Hist. Nat., vol. 5, 1816, p. 260. 

 (Paraguay.") 



The chimango seems more common in the pampas region than 

 elsewhere in its range, as there it is often found in such numbers 

 that it may be said to be abundant. To the northward it is replaced 

 by the allied Milvago cMmachima throughout the Chaco, save in the 

 extreme southern part. Records for M. chimango made during my 

 field work follow: Berazategui, Buenos Aires, June 29, 1920; Vera 

 to Los Amores, Santa Fe, July 5, (the most northern point at which 

 the species was observed); Dolores, Buenos Aires, October 21;

'* The type locality for chimancjo of Vieillot, established by common usage as 

 Paraguay (see Brabourne and Chubb, Birds of South America, vol. 1, December, 1912, 

 p. 63, and Swann, Synoptical List of the Accipitrcs, ed. 2, pt. 1, Sept. 28, 1921, p. 

 16), is in a way unfortunate, as Vieillot, translating Azara"s comment, says that the 

 chimango is rare in Paraguay but common along the Rio de la Plata, a condition that 

 holds to-day.
