Since I wrote the account in my revision of Spix' types some more specimens 

 have come to hand which tend to show that the diiference in size between 

 northern and southern birds is not quite constant. At the same time a better 

 series from various parts of South America should be examined. 



The skins compared by me have the following measurements :

No. 1938. S ad., Goyaz, March 1906.— Wing 162 ; tail 90 mm. 



Agrees with a number of topotypical Bahia specimens in size and coloration. 

 This form ditFers from F. c. choliba (Vieill.) in its paler upper parts and decidedly 

 smaller dimensions.

Not different from Bahia and S. Paulo specimens. The female from Goyaz is

Although I have no topotypical Paraguayan skins to compare, there can be 

 little doubt that these birds belong to the true C. picazuro. Specimens from
