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. Venturi's 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 3 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 alaudinus venturii, 
Leptasthenura cegithaloides berlepschi , Siptornis steinbachi, 
Picumnus cirrhatus tucumanus , Merganetta berlepschi , 
Columba picazuro boliviano , 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.
