A. V. Pelzeln on the Genus Furnarius. 405 



As stated by Messrs. Sclater and Salvin^ this species seems 

 confined to the south, and to occur only in the Argentine 

 Republic, Paraguay (?), and Southern Brazil, whereas the 

 following is an inhabitant of Minas Geraes, Central Brazil 

 (tableland), and probably Bolivia.

* Spix describes the underside of the male ferruginous, that of the 

 female whitish ochraceous. Our specimens show no difference between 

 the sexes ; but there are males with the belly in some cases darker, in others 

 more whitish. A female collected by Natterer (Cuyaba, May 1824) is 

 distinguished by the whitish tips of the feathers on the back and breast, 

 and by the belly being almost white — evidently a tendency to albinism.
