Head-shield of Fulica ardetiaca. 



Tschudi's F. ardesiaca. It turns out, as we had anticipated, to be 

 the same as F. chilensis. Gay; and the species must therefore be 

 called F. ardesiaca, Tschudi's name having the priority. This is 

 quite as well, since, as we have already stated (/. s. c. p. 177), it is 

 very doubtful whether this Coot ever occurs in Chili, the only au- 

 thority for its so doing being Gay's untrustworthy assertion.
