Tinaetor fuscus Max., Beitr., in, 1831, 1106 (part ; female only !). 



Sp. Char. — Above clear brown, becoming bright chestnut on rump 

 and upper tail-coverts; beneath paler, more olive, brown, becoming 

 bright russet on chest (where usually paler shaft-streaks), the throat 

 whitish, with dull brownish margins to feathers; tail dusky. 



Hab. — Brazil, south of the Amazon; west to eastern Peru. 



Adult male (No. 32796, Brazil; Ed. Verreaux). — Above clear mummy- 

 brown, duller (more bistre) on pileum, the rump and upper tail-coverts 

 bright chestnut; wing-coverts margined with rusty brown; tail choco- 

 late-brown basally, deepening towards tip into brownish black. Sides 

 of head similar to pileum, but slightly paler; chin and upper throat dull 

 brownish- white, the feathers indistinctly margined with brownish; lower 

 throat light tawny-brown, the feathers with paler shaft- streaks; chest 

 bright russet, with similar lighter shaft-streaks ; other under parts olive- 

 brown or raw-umber, tinged with brighter brown on sides and flanks and 

 changing to more ruddy brown, or light burnt-umber, on lower tail- 

 coverts. Bill dusky brown, the basal half of under mandible paler; feet 

 dusky brown. Length (skin), 7.70; wing, 3.85; tail, 3.30; exposed eul- 

 men, .90; tarsus, .90; middle toe, .75. 



Adult female (No, 32795, Brazil; Verreaux). — Similar to the male de- 

 scribed above, but smaller. Length (skin), 6,70; wing, 3.50; tail, 2.80; 

 exposed culmen, .90; tarsus; .90; middle toe, .72. 



There are before me nine examples of this species, six of which have 

 no more definite locality attached to them than '• Brazil," while one of 

 them has no indication whatever of locality. The other two are, respect- 

 ively, from Rio Grande do Sul (No. 88453, U. S. Nat. Mus., H. von 

 Jaering, collector), and Chapada, Matto Grosso (No. 33762, Am. Mus. 

 Nat, Hist., H. B. Smith, collector). 



Tinaetor fuscus Max., which is quite universally cited as a synonym 

 of Myiothera umbretta Licht., is so in part only. The two types, belong- 

 ing to the Americau Museum of Natural History, are now before me, 

 and are evidently the identical specimens from which the descriptions in 

 the "Beitrage" were taken. The specimen described as the female is 

 true 8. umbretta, but that described as the male is identical with the Rio 

 Napo bird, identified by Messrs. Sclater and Salvin with S. brunneus 

 Scl., and if not really the latter must stand as a distinct form, S. fuscus 

 Max. (See remarks under 8. fuscus, on page 28.)
