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. Hellmayr
^- 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.

(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.
