This species is a native of Brazil. It is about three 
and a half inches in length. In Lesson’s represen- 
tation, the under mandible of the bill is coloured pale 
pink at the base, then black, then pink and tipped 
with black ; in the description it is mentioned of a 
yellow colour entirely, “I’inferieure jaunatre.” The 
former is a curious distribution. The general colour 
of the plumage is a reddish brown ; on the rump, 
belly, and vent, assuming a sienna colour ; above the 
eye is the pale yellow eye-stripe, beneath the auricu- 
lars, which are black, another ; the centre feathers of 
the tail exceed the others only by about half an inch, 
and become gradually narrower from the base ; the 
projecting part is pure white, the colour of the other 
parts black, the outer one bordered with reddish- 
brown.
