ARGENTINE ORNITHOLOGY. 



Order I. PASSERES. 



Suborder I. OSCINES. 



Fam. I. TUKDID.E, OR THRUSHES. 



EIGHT species of the almost cosmopolitan Thrush-family are known 

 to occur in the Argentine Republic. Of these, five belong to the 

 widely-spread genus Turdus, and are closely similar in structure to our 

 European Thrushes. The remaining three are Mock- birds (Mimin&) 

 a group restricted to the New World, and sometimes considered more 

 nearly allied to the Wrens. They are remarkable as splendid songsters. 

 Burmeister includes in his list a fourth species of Mimus (M. thenca), as 

 found in the Mendoza district ; but there may be some error in this, 

 as M. thenca is only known to us from Chili west of the Andes.
