The birds from the Itio Madeira agree with tlie typical race described from

 in every respect with Guiauau examples.

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 liroad stripe along each side of the throat are glittering golden green. The bird still 

 retains the narrow pointed tail-feat liers 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.

Although the specimen does not any longer exist in the Vienna Museum, the 

 birds of the Madeira district are more probably referable to the Upper Amazonian 

 race than to the typical form, which appears to be restricted to East Brazil
