This is apparently one of the most common species of the family 

 CaprimuJgidce, which inhabits the western countries of South America. 

 The specimen descriljed by Mr. Peale is not in adult plumage. Ac- 

 cording to him, it was obtained near Valparaiso, Chili, in the month 

 of May. " It was sitting on the ground when discovered, and uttered 

 a chick when flushed." 



The figure in our plate is of the natural size.
