 Curytiba, and says that its song is different from that of the 

 Rio bird, which dwells in the swamps {i. e. the next species)"^. 

 In both my specimens the wings are not quite perfect ; but, 

 so far as I can judge by them, the fifth primary is but very 

 slightly shorter than the fourth (as in A. bogotensis) ; and this 

 is decidedly the case in the skin belonging to the Vienna 

 Museum. 



The dimensions of the three specimens are as follows : — 



On the whole, I think it extremely probable that this species 

 is the true " Chii " of Azara, as it is much more likely that 

 this bird of the Pampas should occur in Paraguay than the 

 next-folloAving species, which has not yet been recognized so 

 far south.
