Whatever else this species may be, or whatever other name it may 

 be entitled to, the bird above described appears to be the true Psittacus 

 pileatus, Scopoli, described by him, as above cited, and by Sonnerat, 

 in " Voyage a la Nouvelle Guinee," III, p. 80 (Quarto, Paris, 1776), 

 It is also Psittacus marginatus, Gmelin, but we are not at present pre- 

 pared to say that it is identical with P. olivaceus, Gmelin, figured in 

 Buff. PI. Enl. 287, or properly Psittacus gala, Boddaert (Table dez 

 Planches Enlumineez, p. 17, Utrecht, 1783), notwithstanding that the 

 locality of the latter is given as the Philippine Islands.
