This lovely bird, first described by Latham in his 
General Synopsis, from specimens brought from 
Tonga-Taboo, in which, as well as Otaheite, and 
others of the Friendly Islands, it is found numerously 
disseminated in all their wooded districts, is also met 
with in the Celebes, the Isle of Timor, and in Aus- 
tralia. It is not, however, improbable that other nearly 
allied species have sometimes been mistaken for it, 
as some supposed varieties have been described, 
which it is difficult to reconcile with the usual plu- 
mage of the P. purpuratus. Such, indeed, appears to 
be the opinion of Wagler, who, detailing the plumage 
of both sexes as alike, considers the bird figured by 
M. Temminck, in the “ Planches Coloriees,” for the 
female of this species, to be distinct, and has accord- 
ingly, in his Systema Avium, named it Columba 
xanthognslra, and such also may be the case with
