2. Egretta thula {Molina). 

 Ardea thula, MoL. Sagg. Stor. Nat. Chili (1782). 



Specimens are in the collection from Chili. This species resembles 

 the North American E. candidissima, but is, perhaps, properly to be 

 regarded as distinct, being larger. It is, however, nearly related to 

 that species.

Ardea (jalatea, MoL. Sagg. Stor. Nat. Chili (1782).
