red, having probably been obtained in the breeding-season. This 

 species is at once distinguishable by the under tail-coverts being black 

 with a slight white margin on each side, and the broad elevated 

 frontal shield, which is divided from the base of the bill by a dis- 

 tinct line * (see fig. 2). It may probably be the F. ardesiaca of 

 Tschudi ; but it is impossible to state this with certainty, without 

 reference to the original type. It appears to be uncertain whether 

 this species has ever been met with in Chili, although it is called 

 cAilensis,— both the specimens described by Hartlaub being from 

 Bolivia, and the only other recorded locality being Ecuador (Era- 

 ser) f.

Fulica chik'nsis. 



Dr. SchlegelJ has united F. chilensis with F. sfric/clandi (Hart- 

 laub), which is a very different bird, and seems to have thrown back 

 the whole genus into the confusion from which it was rescued by 

 Dr. Hartlaub's admirable memoir.
