Mr. Keulemans' plate was done from Forster's unpublished drawing in 

 the British Museum, and no specimen is in existence. The legs should, 

 however, be less bright red, more flesh-colour. 



Habitat : Tahiti, but evidently long extinct. 



This bird, according to Forster, was called " Oomnaa " or " Eboonaa," 

 on Otaheite, and the neighbouring islands.
