 Argentine Republic, and Chiquitos and Moxos in Bolivia (d'Orb.). 



U'Orbigny and LatVesnaye in their Synopsis in the Magasin de 

 Zoologie, llartlaub in his Index to Azara, and Bonaparte in his Con- 

 spectus, have all more or less confounded the synonyms of this species 

 with those of the next ; indeed the latter author has united all the 

 synonyms under one head, and I was thus led into the error of de- 

 scribing the present bird as new. It is without doubt however the 

 Azuladillo of Azara, and consequently must bear the specific name 

 ' dumicohd of Yieillot. Lichtenstein's name '■bivittata' belongs to the 

 next species, though the above-mentioned authors have quoted it as 

 synonymous with this.

This species is described by Prince C. L. Bonaparte in his Con- 

 spectus as C. dumicola, from which it may be easily distinguished by 

 its black head.
