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 ap- 

 parent 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.
