“Tris brown, feet dark grey, bill black.” 
The adult male (No. 6), like the type and several examples from Teffé, 
has the pileum and mantle deep cinnamon-rafous, with scarcely any brownish 
suffasion. The two other specimens and an adult female from Bella Vista (right 
bank of the Tapajéz) are somewhat intermediate between S. 7. amazonica and 
S. 7. rutilans. They have the vertex and mantle brown like the latter, but the 
lateral interscapular feathers are entirely or partly ferruginous, and there is a 
decided rufous admixture across the nape. 
The range of S. 7. amazonica is, accordingly, as follows: North-Eastern Peru: 
Xeberos, Chamicuros, Chyavetas (Bartlett), Yurimaguas (Stolzmann). Morth 
Brazil: Teffé, Rio Solimoéas (Hoffmanns); Calama, Rio Madeira (Hoffmanns) ; 
Itaitiba, left bank (Hoffmanns), Bella Vista, right bank of the Rio Tapajéz 
(Snethlage) ; Santarem (Riker). 
S. r. rutilans Temm. inhabits the Rio Negro and Orinoco district (ef. Nov. Zool. 
xiv. p. 13), but occurs also in Lower Amazonia on the ‘banks of the Tocantins. I 
have examined a specimen from Cameta in the Berlin Museum,* and an adult female 
obtained by Miss Snethlage at Arumatheua,t and found them perfectly agreeing 
with my large series from Venezuela, etc. 
Still farther to the east, near Pard and on the Capim and Guama rivers, 
another distinct form, S. 7. omissa Hart., is met with, while a fourth race, S. 7. tertia 
Hellm., dwells in Western Mattogrosso (Rio Guaporé) and in the north-western 
parts of Sao Paulo (Irisanga).

The adult female agrees exactly with Pelzeln’s type-specimens kindly lent by 
_ Dr. von Lorenz, and others from Goyaz, Rio Grande (Northern S, Paulo), ete., in the 
Tring aud Berlepsch Museums. The principal character of S. v. vudpina consists of 
the pileam and upper back being uniform fox-red, in decided contrast to the pale 
olive-brown ramp, ‘Two females taken by Miss Snethlage on the island of Goyana, 
Tapajoz,t are in every respect similar to typical examples, while a single d ad. from 
Arumathena (Tocantins §) is much paler, buffy brown, on the rump. 
In coloration the sexes are alike, but the females are decidedly smaller. The 
Rio Madeira appears to form the western limit of the range of vudpina, since farther 
to the west, on the Rio Purts, another form, S. vulpina alopecias (Pelz. ||) is 
met with.
