INTRODUCTION, XXXV 
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 birds inhabiting New South Wales, Van Diemen’‘s Land, and Swan River, that I have thought it 
unnecessary to figure the whole, but the annexed 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 Grauiina, J veild. 
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 Graucatus, Cur. 
The woods of every part of the Old World from India to Australia 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 subject, I have been induced to regard 
the Van Diemen’s Land bird as distinct, and I have therefore assigned it a name, parvirostris; those of the other 
countries appear to be local varieties or races peculiar to their respective habitats. 
All the members of the group build a flat slight nest of fine short dead twigs, curiously joined together with 
cobwebs, on which they lay two eggs.
