fed on the palm seeds. It was common to see them in flight across
30untiy, their passage announced b}' noisy calls that at a distance have
a ludicrous resemblance to calls for helq) helj). In early morning when
the sun chanced to strike them at the proper angle their beaut i-
fulh' variegated colors of red, yellow, and green showed plainly, but
at midda}^ they appeared as dark silhouettes or, if near at hand,
plain green.
The male taken, when fresh, had the bill dusky neutral gray ; cere
dusky green gray; iris orange chrome, at inner margin shading to
light orange yellow; bare skin surrounding eye pale olive buff; tar-
sus and toes deep mouse gray, the scales outlined with grayish white.
AMAZONA TUCUMANA (Cabanis)
Chrysotis tucuwaim Cabanis, .Jouni. fiir Ornitli., 1S85, p. 221. (Tuciiman.)
Between 1,800 and 2,000 meters elevation on the Sierra de San
Xavier, above Tafi Viejo, Tucuman, on April IT, 1921, these parrots
w^ere common in bands that passed screeching over the forested
slopes or worked about in dense forest growth, well concealed by
heav}^ limbs and abundant foliage. The flocks were wild and seldom
permitted near approach, and only once did a shot offer, when a
female, apparenth^ an immature bird, was taken. The bird secured
has no trace of the red on the tibial region described by Salvadori ^^
in tAvo specimens taken at Lesser, Salta.
PIONUS MAXIMILIANI SIY (Souance)
Pionus Hiy Sovance, Rev. et Mag. ZooL, 1856, p. 155. (Paraguay and
Bolivia.)
From the description of Pionus hridgesi of Boucard*^" it is apparent
that it is a bird in immature plumage of the species Imown
as 7naximiliani. It appears from available material that specimens
of maximiUani from central Brazil are smaller than those from
southern Brazil, Paraguay, the Argentine Chaco, and eastern
Bolivia. The distinction between these has been pointed out by
Souance, who restricted the name maxhrhiliani to the bird of Brazil
and called the larger specimens from Paraguay and Bolivia Pionus
siy from the vernacular name given by Azara. The name of Souance
thus antedates the designation of Boucard, and hridgesi becomes a
synonym of siy.
What I assume to be Pionus vi. inaximiliani is rej)resented in
material seen by skins from Macaco Secco (near Andarahy) and
Santa Rita (State of Bahia), Jacareinha and Rio de Janeiro,
Brazil; it seems to be distinguished from P. rti. siy only by size.
