aware it is not found in South America, and two species are all 
that are known in Australia.

This fine Eagle ranges over the whole of the southern portion of 
Australia and Van Diemen’s Land, but I have no positive evidence 
of its having been seen in the intertropical regions of the country. 
2. Aquila Morphnoides, Gould Vol. I. PL 2. 
A beautiful representative of the Aquila pennata of Europe and 
India. Since the discovery of this bird at Yarrundi in New South 
Wales, when I obtained only a single specimen, T. C. Eyton, Esq., 
has received a second example in a collection obtained at Port 
Phillip, and a third was procured by Captain Sturt at the depot in 
South Australia. 
Genus Ichthyiaetus. 
The members of this genus inhabitlndia and the whole of the Indian 
Islands, and enjoy an equally extensive range over the continent 
of Africa. Their natural abode is the margins of large rivers and 
inlets of the sea; and their chief food consists of fish, dead cetacea 
and carrion.

Found all round the coast of Australia, and said to extend its 
range to India and even to Africa; but this wants confirmation. 
An opinion has been lately expressed that the enormous nests 
observed by Captains Cook and Flinders had been constructed by 
some species of Dinornis ; but it is quite evident from the account 
given by Flinders that they must have been formed by a bird of the 
Raptorial order, and I have no doubt that they were the nests of 
the present bird. 
“ Near Point Possession,” says Flinders, “were found two nests of 
extraordinary magnitude. They were built upon the ground, from 
which they rose above two feet ; and were of vast circumference and 
great interior capacity, the branches of trees and other matter, of 
which each nest was composed, being enough to fill a small cart. 
Captain Cook found one of these enormous nests upon Eagle Island, 
on the east coast.” Subsequently Flinders found another of these 
nests in which were “ several masses resembling those which contain 
the hair and bones of mice, and are disgorged by the Owls in Eng- 
land after the flesh is digested. These masses were larger, and 
consisted of the hair of seals and of land animals, of the scaly feathers 
of penguins, and the bones of birds and small quadrupeds. Possibly
