Parrot tribe is the Pink Cockatoo (Plate XIII. fig. 2, Ca- 
cakia Leadheateri) of Australia. The under side of the body 
and the wings is of a delicate rosy colour^ and the feathers 
of the crest on the head are crimson at the base^ with a 
yellow spot in the centre^ and are white at the tip. Some 
of the cockatoos have the upper mandible much elongated, 
a structure which enables the possessors to grub up the roots 
of the bulbous and other plants on which they feed. The 
Long-billed Cockatoo of Australia {Licmetis nasicus) is one 
of these : the most remarkable however in this respect is the 
Nestor productus, a species now restricted to Philip Island, 
near Norfolk Island. 
No genus or species of the Parrot tribe is more curious 
than the Owl-faced Green Parrot of New Zealand, first de- 
scribed by Mr. G. E. Gray [Stngops hahroptilus, Plate XIII. 
fig. I). This species is nocturnal in its habits, as its some- 
what lurid aspect would betoken. Mr. Strange has pub- 
lished a few particulars of its habits, which are given in the 
^Proceedings of the Zoological Society of London/ No one 
would, at first sight, imagine that the Macaw and Strigops 
belonged to the same natural family. In New Zealand this 
curious bird is called KaJcapo : it resorts, during the day, to 
burrows formed under the roots of trees, or to large masses
