This large series differs from Teffé and Humaytha specimens of P. 2. nigroma- 
culata in the shape of the black markings on the back, and especially on the upper 
wing-coverts, as described by me /.c. p. 388. While, in most specimens, the ground- 
colour above is brighter, a fine golden yellowish olive, some examples from Calama 
are hardly to be distinguished on this score. The amount of white on the bend of 
the wing is much greater than in P. n. nigromaculata. 
Immature birds have the black spots on the ramp less defined and slightly 
edged with rusty, the black colour below is more restricted, etc. Young birds 
(e.g. No, 376) are characterized by the fluffy greater upper wing-coverts having a 
broad central streak of black, reaching nearly to the base, bordered on each side by 
a distinct cinnamon-rufous margin ; the upper parts, too, are rather rufescent brown, 
and the olive-brown of the flanks is far more extended. 
P.n. bowmani replaces the typical form on the right bank of the Rio Madeira, 
ranging eastward to the Tapajéz, where it apparently occurs on both sides of the 
river. I have, however, not yet examined specimens from the type-locality 
(Santarem), and therefore cannot vouch for the correct identification of the present 
series.

“¢ Iris brown, feet brown, bill black.” 
The series is typical of #’. colma, the forehead in the adults being broadly glossy 
black. Below, the black extends down over the chest, as is usually the case in 
Upper Amazonian specimens, but cf. my remarks /.c. It is surprising to find this 
Species also on the right bank, where we should have expected F. ruficeps amazonicus 
alone to occur. This fact suggests their specific distinctness. On his first 
expedition in 1906 Mr. Hoffmanns met with F. colma near Humaytha, left bank of 
the Madeira,
