Young males at first resemble the old females, but are generally 

 more fulvous below, and may be detected by a little black on 

 the wings and tail-feathers, or under the throat-feathers, which 

 form a dusky patch, followed by a whitish patch on the lower 

 throat. 



Although competent authorities assert that specimens from Brazil 

 are absolutely identical with others from Trinidad, from an exam- 

 ination of the fine series of specimens in the British Museum 

 I have arrived at a different conclusion, viz., that there are three 

 well-defined races, perhaps good species, confused under the heading 

 of S. lineola. The typical form witli the white streak on the crown 

 is found in Brazil (Bahia), and extends to Guiana and Yenezuela. 

 In Trinidad it is represented by a race which I call S. trinitatis 

 (fully expecting that a larger series will confirm my determination), 

 which has the w r hite streak on the head represented by a few w r hite 

 spots only. The Amazonian form, which I call S. amazonica, has 

 no white streak and no white spots on the forehead. 



A male of S. amazonica measures : — Total length 3"U inches, 

 culmen 0-35, wing 2-25, tail 1-65, tarsus 0-55. 



The female of S. amazonica is much browner than the female of 

 typical S. lineola, without the olive shade of that species, and is 

 decidedly browner below. Total length 4 inches, culmen 035, 

 wing 1*95, tail 1-6, tarsus - 55.
