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 

 Mendnza, some of which are in Salvin aud Godman's collection. 



In Chili, where it also occurs, Philippi 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 

 ferruginea.

Ten Querquedulce (under which head we embrace the Teals and 

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

 northern species, which visit the Antilles and 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 Querquedulce may be diagnosed as follows : — 



a. Teetricibus alar. min. cseruleis. 



Plaga faciei utrinque alba 1. discors. 



Facie (cum corpore antieo) rubra 2. cyanoptera. 



b. Teetricibus alar. min. fuscis. 



h'. Pileo et cervicis lateribus in mare rubris 3. carolinensis. 



c'. Pileo et cervicis lateribus nigro fasciolatis. 

 c". Rostro sup. ad basin flavo. 



Major: interscapulio dorso fere concolori 4. oxyptcra. 



Minor : interscapulio nigro variegat o 5. flavirosfris. 



d". Rostro tot o nigro 6. andium. 



d'. Pileo fuscescenti-nigro ; cervicis lateribus albis. 



Rostro superiore ad basin rubro 7. versicolor. 



Rostro toto nigro 8. puna. 



c. Teetricibus alar. min. nigris. 



Pileo nigro 9. torquata. 



Pileo fusco 10. brasilicnsis.
