BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 403 
The rectrices are fairly abraded as is so often the case with these 
long-tailed macaws. 
ARA CHLOROPTERA Gray: Red, Blue, and Green Macaw 
Ara chloroptera Gray, List of the specimens of birds in the collection of the British 
Museum, pt. 3, Psittacidae, 1859, p. 26 (British Guiana). 
SPECIMENS COLLECTED 
lad. 9, Brazil, Serra Imeri, December 8, 1930. 
lad. o&, Venezuela, Puerto Ayacucho, Rio Orinoco, January 9, 1930. 
The female is considerably darker red on the underparts than the 
male. 
ARA SEVERA CASTANEIFRONS Lafresnaye: Lafresnaye’s Macaw 
Ara castaneifrons LAFRESNAYE, Rev. Zool., 1847, p. 66 (Bolivia). 
SPECIMEN COLLECTED 
lad. o, Venezuela, San Antonio, Upper Orinoco, March 9, 1931. 
This specimen has a wing length of 243 mm., thereby agreeing in 
size with the race castaneifrons. Peters (Check list of birds of the 
world, vol. 3, 1937, p. 183) writes that birds from the Upper Amazon 
are probably referable to this form, but that birds from the Orinoco 
are typical severa. Apparently the two races meet on the Upper 
Orinoco in extreme southern Venezuela. It appears that the race 
castanetfrons has not been recorded before from Venezuela. 
The present specimen is in badly worn plumage; when freshly 
feathered its dimensions would probably have been still greater. 
ARATINGA PERTINAX AERUGINOSA (Linnaeus): Brown-throated Parakeet 
Psitiacus aeruginosus LINNAEUS, Systema naturae, ed. 10, vol. 1, 1758, p. 98, No. 
12 (America=‘‘ West Indies,”’ er Edwards; Calamar, Lower Magdalena River, 
Colombia, suggested as type locality by Chapman, Bull. Amer. Mus. Nat. 
Hist., vol. 36, 1917, p. 257). 
SPECIMENS COLLECTED 
1 ad. o&, Venezuela, Cerro Yapacana, Upper Orinoco, April 16, 1931. 
lad. 9, Venezuela, Puerto Ayacucho, Rio Orinoco, May 20, 1931. 
These two specimens appear to be closer to aeruginosa than to 
chrysophrys. The male is darker than the female both above and 
below, and also larger. 
ARATINGA PERTINAX MARGARITENSIS (Cory): Margaritan Brown-throated Parakeet 
Eupsittula pertinar margaritensis Cory, Publ. Field Mus. Nat. Hist., Zool. Ser., 
vol. 18, pt. 2, 1918, p. 63 (Margarita Island). 
SPECIMENS COLLECTED 
3 ad. @, lad. 9, Venezuela, Soledad, December 4, 1929, and June 11-12, 1931. 
1 ad. co’, Venezuela, Ciudad Bolivar, June 11, 1931. 
These birds have the brown of the sides of the head distinctly 
paler than chrysophrys, in this respect agreeing with margaritensis.
