have recognized it. Prince Maximilian tells us ( Beitr. iv. p. 932) that 

 he has received examples from Rio Grande do Sul ; and Weisshaupt 

 obtained a series of skins during his excursion from Santiago to 

 Mendoza, some of which are in Salvin and Godman's collection. 



In Chih, where it also occurs, PhiHppi and Landbeck say that up 

 to the present time this species has not been found beyond the pro- 

 vince of Santiago, and that the hunters confound it with Erismatura 

 jerruginea.

 Ten QuerquedulcB (under which head we embrace the Teals and 

 Garganeys) occur within the Neotropical region. Of these two are 

 northern species, which visit the Antilles a"nd Central America in 

 winter ; the remaining eight are endemic Neotropical species, one of 

 which, however, has extended its northern range into the southern 

 portion of the Nearctic region. 



The ten Neotropical Querqtiedulce may be diagnosed as follows :—
