Nab. Central Brazil : near S. Leopoldina on the upper Rio Aragnay, Goiaz. 



S ad. Differs from that of S. c. columbiana in its smaller size, very much 

 smaller and weaker bill, slightly more yellowish green back and decidedly brighter, 

 fiery orange-red frontal patch. The under surface is of the same bright yellow, 

 but the sides of the chest lack the greenish tinge ; the cheeks are yellowish olive 

 like the back, as in «S'. c. columbiana. 



Two <$S ad. measnre : wing 58 ; tail 40 ; bill 9A — 10 mm. 



? ad. Differs from that of the typical form in being smaller, the bill especially 

 so, and in being paler everywhere. The upper parts are paler and more greyish 

 brown, the lower ones more whitish, the chest and sides very slightly shaded with 

 brownish. 



Two ? ? ad. : 55, 57 ; tail 41 ; bill 9 mm. 



c. Sicalis columbiana goeldii Berlepsch. 



Bab. Lower Amazons : Paricatnba, Urncurituba and Itaituba, near Santarem ; 

 Manaos ; Eastern Pern : Yana-yaeo, a tributary of the Ucayali River. 



S ad. Differs at a glance from the two foregoing forms by having the lower 

 parts of a much brighter, orange yellow colour, which is spread also over the cheeks 

 and ear-coverts. The fiery orange-red of the forehead extends over the whole vertex ; 

 the nape and the rump are much brighter, of a golden olive yellow ; and the quills 

 are more distinctly edged with pale yellowish on the inner webs. The bill is stout 

 and large, as in S. c. columbiana.

? ad. Agrees in the paleness of the uuder parts with that of S. c. leopoldinae, 

 but has longer wings and a very much larger bill. Besides, the flanks are washed 

 with bnffy yellowish, the axillaries and under wing-coverts more yellowish, and the 

 inner webs of the quills more distinctly edged with yellowish white. Wing 59; 

 tail 42; bill 11 mm.

Agrees well with specimens from Upper Amazonia, but seems to be somewhat 

 smaller. This, however, may be due to its being in very worn plumage. Additional 

 examples are required to prove whether the Lower Amazonian form is really 

 identical with that found in Peru, etc., or not. 



I have shown, in the paper quoted above, that the proper name of this species 

 is M. aurifrons.
