Obs. This new form agrees with C. p. platensis (Lath.) in 

 having the rump variegated, and both webs of all the rec- 

 trices banded with black and brown, but it differs in the 

 uniform crown (not striped with black and fulvous-brown), 

 the barred sides of the belly, the white (instead of rufescent 

 buff) sides of the head and neck, shorter tail, &c. 



According to our present knowledge, the following 

 geographical races of C. platensis can be recognized : — 



a. C. p. platensis (Lath.). Eastern Argentina, from the 



mouth of the La Plata (Buenos Aires) south to Pto. de 

 San-Blas, and west to Mendoza. 



b. C. p. eidouxi (Bonap.) . Chili, Southern Patagonia, and 



Falkland Islands. 



c. C p. graminicola, Tacz. Central and South-eastern 



Peru and Northern Bolivia. 



d. C. p. polyglottus {YieiW.). Paraguay and South-eastern 



Brazil. 



e. C. p. alticola, Salv. & Godm. Mount Roraima, British 



Guiana.
