Birds of Celebes: Treronidae. 
distinct. In Celebes its compatriot, O. loallacei, may be distinguished from it by 
Its two niiddk tail-feathers being yellow-green, not grey with a subterminal bar, 
by the blackish bar crossing the other tail-feathers near the middle in O. wallacei 
and close up to the end in O. vernans, by the larger bill of O. waUacd and, in 
the males of that species, by the green neck, maroon back, and by the absence 
of the orange patch. 
Local differences in O. vernans have been suggested and species named 
accordingly, but Count Salvador!, after an exhaustive study of the literature 
and 130 specimens in the British Museum, unites them again, remarking that 
“some specimens have the forehead and throat more or less tinged with greenish, 
but they are not confined to a particular locality”. 
GENUS PTILOPUS Sw. 
Ihe Painted Pigeons vary in size from the dimensions ,'of a small Thrush 
to those of a Rock-dove. The tarsus is feathered almost to the foot. Wing 
moderate, relatively shorter than in Osmotreron and Carpophaga. Tail rounded, 
shorter than the wing, 14 rectrices (in one subgenus 16). Colour chiefly green’ 
patches of other bright tints generally occurring on the head, throat, breast’ 
or elsewhere. In two of the three subgenera occurring in Celebes, Leucotreron 
and Lamprotreron the first primary is suddenly attenuated in its terminal third’ 
and to some extent in the subgenus Ptilopus also. 
The genus ranges [from the Malay Peninsula throughout the Archipelago 
to Australia and the high islands of Polynesia.
