The birds from the Rio Madeira agree with the typical race described from 
Pard. 
P. t. theresiae (Da Silva) inhabits Cayenne, Surinam, British Guiana, the whole 
of Lower Amazonia from Para west to Manzios (Barro do Rio Negro), and the 
banks of the Madeira and Tapajéz Rivers, Natterer’s series from Manos agrees 
in every respect with Guianan examples.

Wing 67; rectr. med. 48, ext. 35; bill 184 mm. 
Agrees with South Brazilian skins except that the bill is very slightly longer. 
The median portion of the throat and foreneck is white, while a small chin-spot and 
a broad stripe along each side of the throat are glittering golden green. The bird still 
retains the narrow pointed tail-feathers of the juvenile plumage, with a distinct 
bluish black bar near the base of the three outer pairs, but in other respects it 
is adult. 
New to the fauna of the Rio Madeira. Kalinowski had obtained it in the 
Chanchamayo district of Central Peru. t

Although the specimen does not any longer exist in the Vienna Museum, t e 
birds of the Madeira district are more probably referable to the Upper veers 
race than to the typical form, which appears to be restricted to Rast Brazi 
(Bahia to 8. Paulo).]
