o- Besides the six extinct West Indian species characterized in the ' ' Key, ' ' another 

 species of Ara formerly existed on the island of Dominica. This has been named Ara 

 atwoodi by Mr. Austin H. Clark (Auk., xxv, July, 1908, 310, in text), but so little is 

 known of the bird that the characters mentioned are exceedingly vague, and I am 

 therefore unable to place it in the "Key." It is mentioned in "The History of the 

 Island of Dominica" (1791), by Thomas Atwood, after whom the species is named.
