plumage, which he says certainly seems different from the C. leadbeateri from farther 
south.

Moultling. — The specimens taken during the period from ”/12 1910—""/1+ 1911 
are all in moulting. Pins of the secondaries in some of them. All have the back 
more or less dirty in colour, due to extraneous influence of sandy dust, which has 
powdered and soiled those parts of the feathers that have been chiefly lying in the 
surface. But here we have evident bleaching-phenomenon too, and in the specimen '"/s 
the superficial parts of the back-feathers are lighter than the underlying parts. Other 
feathers have a deeper gray unbleached colour. The specimen is on the whole lighter 
than the others, which nevertheless also show this difference. 
Moulting-season. — Dec., Jan. according to the specimens shot. The specimen 
"/s does not show any sign of moulting. 
Fcological. — One of the most common birds of the bush. It was very fre- 
quently seen at »the billabongs», where it filled the air with its scream and flew in 
flocks of hundreds from place to place. It often stayed on the ground. 
Licmetis pastinator GouLD. 
Math.; handl. n:r 326. > Si ad., 2 ad: Derby, Kimb. 2/5 1911. 
Ecological. — This was the most general of all the cockatoos. It appeared 
in flocks of thousands and also in smaller flocks of fifties or hundreds. TIt preferred 
to keep around pools of water (billabongs and such places), where especially in the 
evenings and mornings it made a deafening noise. These white flocks thus contri- 
bute to a great extent to the life in the bush, where in many places, as it were, 
they formed part of the landscape. It was also common at Sunday Island, and 
straggling crowds sometimes came to visit even neighbouring islands (according to 
the missionary S. HADLEY). 
The bird seems to find its chief food on the ground, where the flocks were 
often seen in the course of the day. They were particularly shy and it was very 
hard to approach them.

Juvenals. — Three specimens are juvenals or younger birds. A young moulting 
male with female plumage seems to have been born this year. It differs from the
