35. Hartert and Venturi on Argentine Birds. 



[Notes sur les Oiseaux de la Republique Argentine. Par E. Hartert 

 et S. Venturi. Nov. Zool. xvi. p. 160 (1909). J 



The collection made by M. Venturi, of Buenos Ayres, in 

 various parts of the Argentine Republic, and acquired by the 

 Tring Museum, contains 1115 bird-skins and several thousand 

 eggs. The species have been determined by Mr. Hartert, 

 while M. Venturi has supplied abundant field-notes. The 

 authors have not attempted to make a complete list 

 of Argentine birds, but treat only of the specimens in 

 M. Venturis collection and in seven other Argentine collec- 

 tions in the Tring Museum. Nevertheless there cannot be 

 very many species omitted, because 509 species and subspecies 

 are enumerated, and Sclater and Hudson's ' Argentine 

 Onithology ' contains only 434 species. The series of 

 interesting field-notes by M. Venturi have been translated 

 from the original Spanish into French, while Dr. Hartert 

 supplies the scientific remarks. The following species and 

 subspecies are described as new : — Cistothorus platensis 

 tucumanus, Anthus hellmayri, Phrygilus alaudinvs venhirii, 

 Leptasthenura agithaloides berlepschi, Sipto7'nis steinbachi, 

 Picumnus cirrhatus tucumanus, Merganetta berlepschi, 

 Columba picazuro boliviana, and Nothura salvadorii. 



Seventy excellent figures of eggs on two plates accompany 

 the text. The field-notes on the parasitic Cow-birds (Molo- 

 thrus, p. 184) are of special interest.
