Birds of Celebes: Campophagidae. 
Campophagidae appear to have been long settled in the Indo-Australian area as 
shown by the barred plumage of certain species of Graucalus which are found 
in both quarters. The young of the more highly specialized G. leiicopygius re- 
verts to this barred type of dress. G. bicolor and G. temmincki are well differen- 
tiated and, therefore, perhaps rather ancient insular forms. In any case these 
I'egarded as older inhabitants of Celebes than Lalage leuco-
