In all the specimens the inner webs of the five outer rectrices are pale yellow 

 at the base, this colour being entirely concealed by the tail-coverts ; on the median 

 pair the corresponding portion is pale greyish brown, sometimes with a yellowish 

 tinge. The outer web of the outermost rectrix is invariably pale yellowish grey. 

 In Nos. 2135 and 1853 the tail-feathers terminate in a broad, though ill-defined, 

 apical band of pale brownish or brownish white, while in the remaining specimens 

 there is but a narrow l)rownish margin to be seen. 



The colour of the rump and upper tail-coverts is extremely variable. In 

 No. 1852 they are uniform light yellowish green ; in Nos. 2163, 2164, and 2165 

 the rnmj) is pale greyish yellow, the upper tail-coverts rather purer brownish grey ; 

 while in Nos. 2135 and 1853 both are clear brownish grey, as in the type of 

 S. a. bahiaeX (Berl.). 



No. 2135 diflers from the other examples by its much shorter and broader bill, 

 a peculiarity indicating immaturity in allied genera of Tyrannidae, though, judging
