pp. 64 and 81.

The accumul

ation of so large a mass of materials is readily accounted for when we remember that the bird is in
the habit of resorting to the same eyry for a long succession of years, and of annually carrying additional materials

to reconstruct the nest.
I myself found and took young birds of this species from similar nests placed on the points of rocks and

promontories of the islands in Bass’s Straits.
Genus Hauiastur, Selby.

The range of the members of this genus extends over Australia and all the islands to India.

Haliaétus (Ictinoaétus) leucosternon, Kaup, Isis, 1847, p. 277.
Confined, so far as I am aware, to Australia, and forming a beautiful representative of the Haliastur
Ponticerianus of India.

Milvus sphenurus, Swains. Class. of Birds, vol. i. p. 211.
Haliaétus (Ictinoaetus) canorus, Kaup, Isis, 1847, p. 277.

Inhabits all parts of Australia yet visited by travellers, even the Depot in the interior.
Genus Panpion, Sav.

Of the genus Pandion four species are now known; one inhabiting America, another Europe and Asia, a third
the Indian Islands, and the fourth Australia.

This species of Pandion performs precisely the same office in Australia that the P. haliaétus does in Europe and

the P Carolinensis in America; to both of which species it 1s very nearly allied.

As they are the most typical of all the Hawks, so are the members of the genus Falco the most universally
dispersed over the face of the globe ; and I question whether the law of representation is in any case more beautifully

and clearly shown than by the members of the present group.

Up to the present time only four examples of this fine Faleon have been procured ; it is a species admirably

India, Europe, and North America on the one hand, and Cape Horn, the Cape of Good Hope and Australia on

varieties of each other ; but I agree with the Prince of Canino and Professor Kaup in considering them to be distinct
