 Remarks. -There has been much uncertainty in regard to the 



range of true melancholicus. We refer to this form all bird> from 

 Argentina and Uruguay northward to western Colombia and to South 

 Brazil. Birds from western Colombia and western Ecuador are, a- a 

 matter of fact, intermediate in coloration, between true melancholicus 

 and the form inhabiting northern South America. Like true melan- 

 cholicus they possess the wide chest-band, which, however, is slightly 

 more yellowish in tone, not so grayish. On the whole, they are very 

 close to true melancholicus and hardly distinguishable in parallel scries. 

 The difference is certainlv too small to warrant further subdivision.
