partei upon, it is of course impossible to know whether it ought to 

 be applied to the present or to the Tonga-Tabou bird. As however 

 I now have selected the Balaou species as the type of bonapartei in 

 order to avoid giving it a new name (for it is quite distinct from the 

 Pt. purpuratus, Wagl.), and as the type will be in the collection of 

 the 1 ans Museum for future reference, it will not be difficult here- 

 after to ascertain what the species really is. The type is unique 



Adult Front and crown rosy purple, faintly margined posteriorly 

 with yellow ; throat white ; occiput, neck, and breast ash-colour 

 tinged with green ; abdomen and flanks green ; an indistinct dark 

 green spot in the middle of the former. Back and wings green 

 with strong coppery-red reflexions. Inner secondaries with a small 

 dark green spot at tips, and all edged with yellow. Primaries dark 

 coppery red, edged with white. Tail above green, with bright 

 coppery-red reflexions, and with a subapical greyish-white band • 

 beneath dark grey, with a broad apical white band. Crissum and 

 under tail-coverts bright yellow. Bill greyish black, with yellow tip. 

 Feet light red. Total length 9 inches, wing 5|, tail 3k culmen K
