All the upper surface, wings, and tail black ; under surface 
brownish black, tinged with grey on the abdomen ; under tail-coverts 
and tips of all but the two centre tail-feathers white ; irides yellow ; 
bill and feet black. 
Total length, 19 inches ; bill , 2 ; wings , 11 ; tail, 9 ; tarsi, 2J-. 
This species inhabits South Australia, and is distinguished from 
all its congeners by the total absence of any white mark on the 
wings ; in other respects it is so similar to S. Arguta , that I have 
not considered it necessary to give a figure of it. 
Genus Gymnorhina. 
Like Strepera this is strictly an Australian form, all the species 
of which frequent exclusively the southern parts of the country. 
Their structure is a mere modification of that of the members of the 
last genus adapted to a somewhat different mode of life and habits. 
They are more pastoral than the Streperce , frequenting as they do 
the open plains and grassy downs, over which they run or rather hop 
with great facility. Their chief food consists of grasshoppers and 
other insects, to which berries and fruits are added, when such kinds 
of food are procurable. If unmolested in their natural haunts they 
may be considered a more familiar race than the Streperce , but if 
persecuted they become extremely shy and distrustful. Few birds 
are more ornamental, or give a more animated appearance to the 
country than the members of this genus, either when running over 
the surface of the lawn-like ground, or when pouring forth their 'sin- 
gular choral-like notes while perched together on the bare branches 
of a fallen Eucalyptus. The form and situation of the nest is the 
same as those of the Streperce , larger, but not unlike that of the 
European Crow. 
Specimens of this form from Western Australia exhibit some tri- 
fling differences, but I have not as yet been able to satisfy myself 
whether they are or are not distinct.

Genus Cracticus. 
The members of this genus, which are universally dispersed over 
Australia, prey upon small quadrupeds, birds, lizards and insects, 
which they frequently impale after the manner of the ordinary
