Juvenals. — Different from the adults. Both the young female and the young 
male are brownish black also on the underpart with only a few ferruginous brown 
feathers. 'Throat in the young male black, the chin with small black feathers with 
white centres. The young female whitish buff on the throat and chin, transitory 
in chestnut on the lower part of the throat. It is noticeable that the juvenals are 
black on the underpart and grow lighter at the transition of the plumage from that 
of the juvenals to that of the adults. 
Moulting. — All the specimens are in moulting at very different times of 
the year. 
FEcological. — Appeared at the water-pools in the bush round Mowla Downs, 
Derby and in Dampier land. Was missing at Sunday Island. The bird often made 
its presence known by a loud, sharp whistling.

Ecological. — This tree-runner, which was widely spread in the woods of the 
continent, always appeared, where I saw it, in small flocks of about 4—6 or more 
members. It was also seen together with Diceum and Climacteris, with which it 
seemed to be wandering about looking for insects (Mowla Downs), which naturally 
reminds one of the habits of the European Certhia familiaris (L.), Sitta sitta (L.) 
and certain of our Parus-species.

Ecological. — The yellow-white eye was common in the richer bush-vege- 
tation and in the mangrove nearest the shore at Sunday Island, the only place 
where I have observed it. It was one of the best singers, and it often delivered its
