maries and all the superior wing-coverts, excepting the primary coverts, 
margined with pale dull brown, these edgings darker and more rufescent 
on the lesser coverts; sides of head and neck like the upper parts, but 
somewhat more grayish; lores paler and somewhat buffy grayish; throat 
and jugulum pale smoke gray; lining of the wing barium yellow, some- 
what clouded by brownish gray; remainder of lower parts pale primrose 
yellow. 
Measurements.—Male: wing, 94.5 mm.; tail, 88; exposed culmen, 16.5. 
Female: wing, 83.5 mm.; tail, 83.5; exposed culmen, 17. 
Type locality——sSoutheastern Brazil. 
Geographic distribution.—Southeastern Brazil, north at least to Ba- 
hia, probably also to Pernambuco. 
REMARKS.—This race has already been revived by Mr. Hellmayr,' 
under the name Myiarchus ferox cantans, and it apparently can be dis- 
tinguished from both Myiarchus ferox ferow and Myiarchus ferox fero- 
cior. From Myiarchus ferox ferow it differs in its smaller, paler bill, 
its much paler, more grayish or brownish (less greenish), and more 
uniform upper parts, and in its paler ventral surface. How far to the 
northwestward in Brazil it ranges remains yet to be determinéd. 
Whenever recognized, this race has been known as Myiarchus ferox 
cantans Pelzeln, but it should apparently be called Myiarchus ferox 
swainsoni. Cabanis and Heine, in describing their Myiarchus swainsoni, 
gave as its locality only Brazil, and they included in their literature 
citations also localities that belong under Myiarchus ferox ferocior; but 
the diagnosis is clearly applicable to the bird from southeastern Brazil, 
called later Myiarchus cantans by von Pelzeln.* Since Myiarchus swain- 
soni Cabanis and Heine has several years’ priority over Myiarchus can- 
tans Pelzeln, it is the name that should be used for the present sub- 
species.
