INTRODUCTION. XXXVI] 
rome the ground: they all build a neat, round, cup-shaped nest, and the eges are generally fowr in number 
Their powers of flight are not great: some of the species enjoy a wide range of habitat, while others are extremely 
local. The song of some is loud and rather pleasing, while others merely emit a whistling note, slowly but 
frequently repeated.

The two birds described by me in the Proceedings of the Zoological Society, Part V. p. 164, as P. wantho- 
procta and P. longirostris, are both immature birds, and are, I believe, from Norfolk Island. 
Genus Coniuricincia, Vig. & Horsf. 
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 restrictedly its own. They 
have many characters in common with the Pachycephale, which they also resemble in their actions, food, economy 
and nidification. They are neither Shrikes nor Thrushes, but are most nearly allied to the former; they are 
insect-feeders to a yery 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.

South Wales; it may hereafter prove to be identical with the last-mentioned species, C. parvula, the form and
