Shrikes. Their nidification resembles that of the species belonging 
to the genera Strepera and Gymnorhina , the nest being a large 
round structure placed among the branches of the trees, and the eggs 
four in number. So great a similarity exists between the species 
inhabiting New South Wales, Van Diemen’s Land, and Swan River, 
that I have thought it unnecessary to figure the whole, but the an- 
nexed descriptions, with a due attention to the localities, will obviate 
all difficulty in determining the species.

Vanga cinerea , Gould in Proc. of Zool. Soc., Part IV. p. 143. 
Inhabits Van Diemen’s Land, and may be distinguished from 
C. destructor by its much longer bill, and, when fully adult, by its 
grey back. 
96. Cracticus leucopterus, Gould. 
Inhabits Western Australia ; is of the same size as C. destructor , 
but has the white mark on the wings much larger and more clearly 
defined.

Genus Grallina. 
Only one species of this genus is at present known. It is peculiar 
to Australia, over every portion of which country it is dispersed; 
and it may be considered one of the anomalies of the Australian 
ornithology, since its alliance to any group of birds with which we 
are acquainted is very remote.

Genus Graucalus. 
The woods of every part of the Old World from India to Austra- 
lia are tenanted by species of this genus, which, from their great size, 
their being strictly insectivorous, and individually very numerous, 
must tend to keep insect life in check, and consequently perform a 
most important part in the economy of nature. 
In my description of Graucalus melanops, I have stated that New 
South Wales, Van Diemen’s Land, Swan River and Port Essington, 
are each inhabited by Graucali so nearly allied to each other that 
it was questionable whether they were not one and the same species, 
and that the slight differences they present were attributable to some 
peculiarity in the districts they inhabit ; after much attention to the
