Four specimens were collected of which three, a male, a female, and 

 an alcoholic specimen whose sex is not known at present were taken 

 at Xukuhiva, Marquesas Islands, on 16 September, 1S99. The fourth 

 is a mummy that probably should bear the same date. These birds 

 differ from the original description in having the shafts of the rectrices 

 blackish (not entirely white). In addition the second rectrix is the 

 longest instead of the third as is stated by Saunders. The black eye 

 ring is more distinct than in specimens of Gygis alha.
