short, third, fourth and fifth longest and equal ; tail moderate, nearly 
equal ; feet robust, hind-toe strong and longer than the middle one, 
outer toe united at its base to the middle toe ; claws hooked. 
The genus Acanthogenys , of which only one species is known, 
presents us with a form intermediate in size and in structure between 
the smaller Honey-eaters ( Meliphagce , Ptiloti , &c.) on the one hand, 
and the larger kinds ( Anthochcerce ) on the other.

This species is widely distributed over the interior of the southern 
portion of Australia, from east to west ; the sexes are alike in plumage, 
and the young are very similar, but are destitute of the spines on the 
cheek, which are scarcely assumed during the first year. Th eBanksice 
are the trees mostly frequented by this bird, the presence of which 
is indicative of sterile sandy districts. 
Genus Anthoch^ra. 
A genus peculiarly Australian, three species of which are exclu- 
sively confined to the southern or extra-tropical parts of the country, 
and one to Van Diemen’s Land. 
These four birds might with propriety be separated into two 
genera, those with auricular appendages, A. inauris and A. carun- 
culata, having many characters differing from those of the A. melli - 
vora and A. lunulata.

Genus Tropidorhynchus. 
The law of representation in Australia appears to be chiefly con- 
fined to the species inhabiting the eastern and western coasts, but 
in this case it takes the opposite direction, or north and south, for 
a more singular and perfect representation cannot be found than the 
T. corniculatus and T. citreogularis of the south-eastern parts of 
the country, are of the T. argenticeps and T. sordidus of the north- 
western. Extra Australian species inhabit New Guinea and the 
neighbouring countries.

312. Tropidorhynchus sordidus. 
Inhabits the Cobourg Peninsula, and is precisely similar to T. citreo- 
gularis, but is smaller in all its admeasurements except in the bill, 
which is more developed.
