No. IOCS. ? ad., Manicor^ (Las Oncas), 20. viii. 1908.— Wing 88 ; tail 59 ; 

 hill 19i mm. 



This large series difters from Teft'i^ and Humajtha specimens of P. rt. nigroma- 

 culaia in the shape of the black markings on the back, and especially on the npper 

 wing-coverts, as described bj- rae I.e. p. 388. While, in most specimens, the gronnd- 

 colour above is brigliter, a tine golden yellowish olive, some examples from Calama 

 are hardly to be distinguished on this score. The amonnt of white on the bend of 

 the wing is much greater than in P. n. nigromaculata. 



Immatnre birds have the black spots on the nirap less defined and slightly 

 edged with rnsty, the black colonr below is more restricted, etc. Young birds 

 {e.g. No. 376) are characterized by the flnfty 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 rnfescent brown, 

 and the olive-lirown of the flanks is far more extended. 



P. n. howmniii replaces the typical form on the right bank of the Rio Madeira, 

 ranging eastward to the Tapaj6z, 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.

 remains unique in the Tring Museum.]

The series is typical of 7". 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 I.e. It is surprising to find this 

 species also on the right bank, where we should have expected F. vuficeps amazonicus 

 alone to occur. This fact suggests their specific distinctness. On his first 

 expedition in 1900 Mr. Hoflmanns met with F. colma near Humaytha, left bank of 

 the Madeira.
