No, 1062. 3 ad., S. Vicente, Falls of the Rio Machados, 1. viii. 1908.— Wing 
- 121; tail 66; bill 23 mm. 
“Tris brown or dark brown, feet and bill yellowish grey.” 
This species had never been met with since Natterer’s time, who obtained ten 
specimens in the same district many years ago. LB. chrysosema is most nearly 
allied to B. tuipara (Gm.), but differs at a glance by having the greater upper 
wing-coverts golden yellow instead of orange. Moreover, the reddish frontal edge 
is of a clearer, more orange tint, the orange-red chin-spot rather larger, and the 
wings are somewhat longer. The other differences mentioned by Dr. Sclater— 
viz. the more yellowish green colour of the plumage and more bluish crown—are 
not borne out by Mr. Hoffmanns’ series. The couple from Calama show but a very 
narrow reddish frontal edge, while in the two Machados birds it is fully as broad 
as in B.tuipara. In the males the crown (as far back as the posterior margin of 
the eye) is more or less washed with pale bluish, whereas the female has the top 
of the head nearly uniform green. 
B. chrysosema is very likely a geographical representative of B. tuipara. 
Up to the present time it is only known from the right bank of the Upper Madeira 
(Pederneiras to Calama) and its tributary, the Rio Machados. 
B. tuipara inhabits the Lower Amazons from Pari to Mandos. Mr. Hoffmanns 
obtained it at Urneurituba, left bank of the Rio Tapajéz,* Miss Snethlage at 
Arumatheua, on the Tocantins.t The Manich Museum has lately received five 
specimens from Miritiba, Maranhio, through Mr. F. Schwanda.

No. 194, (?), Calama, 8. vii, 1907.—Wing 220; tail 125; bill 41 mm. 
“Tris yellow (3), brown (?), feet black, bill grey.” 
The male has the crown uniform light green, while in the other example the 
forehead is slightly spotted with yellow. Of two adult males obtained by Natterer 
at Borba, one has a well-defined bright yellow patch on the anterior crown, the 
other has the upper part of the head uniform green. In another paper t I have 
already alluded to the variability of this character, which appears to be purely 
individual, not geographical. The Madeira birds agree, in size and coloration, with 
a topotypical example from Cayenne and others from Para, 
Specimens from Chiriqui and Western Keuador do not show the mealy appear- 
ance of the upper parts so conspicuous in eastern birds, and may, if this difference 
be found constant, be separated as A. farinosa inornata (Salvad.), §
