Dendrocygna fulva, according to Burmeister, is found in the 

 eastern and northern districts of the La- Plata ba^in, on the rivers 

 Uruguay and Parami, and as far north as Tucuman ; and Azara 

 observed it both in Paraguay and in Buenos Ayres. In the Brazilian 

 empire it was obtained by Prince Maximilian on the river Behnonte 

 and also on the sea-coast near Porto Seguro ; but although Burmeister 

 states that it is found throughout Central Brazil, Natterer seems to 

 have failed to secure specimens. It appears, so far as we know, to 

 be absent from the basin of the Amazons and from the whole of the 

 northern portion of the southern continent ; nor is it found in 

 Central America or in the West Indies. In Mexico it reappears, 

 and would seem to be by no means rare, occurring from the Rio- 

 Grande frontier and California to Mazatlan and the valley of Mexico. 

 Singular as this distribution is, it is still more remarkable when we 

 consider that there appear to exist no tangible grounds for separating 

 the American bird from that called D. major by Jerdon, which 

 ranges throughout the peninsula of India and is also found in Mada- 

 gascar !
