The last reference is placed with the synonymy of this form, not because I believe 

 the form untenable but because I have not the necessary material for a clear under- 

 standing of the South American forms. However, one of the characters ascribed to 

 T. s. fortis can not be relied on, namely, the entire absence of black on inner web of the 

 outermost rectrix, one specimen from Chapada, Mattogrosso, southwestern Brazil, not 

 having a trace of the usual black spot.
