VERTEBRATA. 
THE BATABA. 
THE MAGPIE SHRIKE. 
being thirteen inches long. The upper parts are hlacTs:, "broadly banded with fulvous ; beneath it 
is whitish brown. Other species belong to Africa and Asia. 
Genus BETHYLUS : Bethyhis. — This includes the Magpie Shrike, B. picatus — -Lanius pic- 
atus of Latham — ^found in Guiana and Brazil. It resembles the magpie in appearance. 
In Australia, there are three genera of shrikes : those of the Genus FALCUISrCULUS, 
feed on insects, in order to obtain which they strip the bark off the trees with their strong bills. 
The Falconelle, F.'frontatus^ is of the size of a sparrow, and in its form and markings resem- 
bles the great titmouse of Europe. Another Australian species, the Oreoica cristata, is distin- 
guished for hopping about on the ground, which is rare with other members of this genus. It 
has a sort of ventriloquial power of voice, commencing a song in a low tone, which seems to come 
from a great distance; but it gradually increases in strength, till the listener at last discovers that 
the bird is very near at hand, perhaps immediately over his head. This kind of ventriloquial power, 
however, by which the hunter is often deceived, is possessed by many other birds. 
THE AlVIPELIDiE OE CHATTEEEES. 
The Ampelidce embrace several groups, resembling the True Chatterers in certain respects, and 
hence they are associated with them. For the most part they belong to the warm parts of the 
world, and live on insects. 
THE PIPRIN^ OR MANAKINS. 
This group is composed of numerous beautiful birds, mostly of small size, all of which, except 
the Cahjptomena viridis, found in Sumatra, inhabit the tropical regions of the American continent. 
They live in small flocks, in the hot, moist forests which spread over those torrid countries, and 
feed upon insects and fruits. They are exceedingly active in their movements. 
Geyius RTJPICOLA : Rupicola. — Of this is the Cock of the Rock, R. aurantia, about the size 
of a pigeon, and of a fine orange color, with the quills of the wing and tail blackish. It is dis- 
tinguished by a singular crest of feathers arranged in two planes, rising from the sides of the 
head so as to meet in the middle, forming a semicircular wedge-like ornament, which projects in
