This Thrush lias been united by different authors with T. albiventris, T. crotopezus, and even 

 with the very distinct T. rufiventris, of which d'Orbigny gravely tells us that it is the female. 

 The confusion thus caused has led to its having received three additional names besides 

 the one originally bestowed upon it by Vieill ot. We hope that the figure of it herewith 

 given^ under what we believe to be its oldest designation, will render it easily recognizable 

 by future Ornithologists. 



Azara's description of his Zorzal obscuro y bianco is, we must admit, as Dr. Cabanis has 

 already complained, a little obscure, but the fact of this being the only member of the section 

 found in Paraguay and the Argentine Eepublic leads us to believe that it is in all probability 

 Azara's species. It is certainly Turdus amaurochalinus of Cabanis, as a specimen of it thus 

 marked in that author's own handwriting is in Sclater's collection. Spix appears to have 

 figured this bird as the female of his T. albiventris, and Sclater employed the same term for it 

 in his " Synopsis of American Thrushes," not being then acquainted with the bird legitimately 

 entitled to bear that name, of which we shall give a drawing in our next part. In both his
