The two birds described by me in the Proceedings of the Zoolo- 
gical Society, Part V. p. 164?, as P. xa.nthoprocta and P. longirostris 
are both immature birds, and are, I believe, from Norfolk Island. 
Genus Colluricincla. 
Like the last group, the present is strictly confined to Australia, 
every one of the colonies of which country, from north to south and 
from east to west, is inhabited by a species peculiarly and restrict- 
edly its own. They have many characters in common with the 
Pachycephala , which they also resemble in their actions, food, eco- 
nomy and nidification. They are neither Shrikes nor Thrushes, but 
are most nearly allied to the former ; they are insect-feeders to a very 
great extent, but occasionally partake of mollusks and berries. Some 
of them defend themselves vigorously with both bill and claws when 
attacked. Their voice is a loud whistle, some parts of which are not 
devoid of melody, particularly the loud swelling notes. 
The nest is rather slightly built, round and cup-shaped in form, 
and is mostly placed in the hollow spout of a tree : the eggs are four 
in number.

p. 80. 
I have assigned this name to a bird lately sent to me by Mr. 
Strange from the brushes of the Clarence in New South Wales ; it 
may hereafter prove to be identical with the last-mentioned species, 
C '. parvula , the form and admeasurements being precisely the same ; 
but the bird from New South Wales has a lighter coloured bill, and 
the whole of the under surface washed with deep rufous.
