INTRODUCTION. 
Ixix 
and other lierbage are sufficiently dense and the leaves of the trees sufficiently forward to screen it from 
sight. Common in England and the south of Scotland, but seems to be more rare in the north of that 
country ; and in Ireland, according to Thompson, it is extremely so. 
Genus Troglodytes. 
In the Old World the northern regions are those that are principally inhabited by the members of this 
genus ; in the New they range from the northern to nearly the southern extremity of the great continent 
of America. They are pert, lively little birds, which differ from the true SyhicB in many particulars, 
rendering it very difficult to assign them a place affinitively in any of the j3roposed systems.

Common Wren. 
As implied in its specific appellation, this bird is a native of Europe, over which it is very generally 
dispersed and strictly stationary, inasmuch as it keeps in the vicinity of its breeding-place from year’s end to 
year’s end. 
Family CERTHIIDiE. 
The members of this singular bark-loving family, which are but few in number, frequent the temperate 
regions of both the Old and the New World. Four species inhabit the great Himalaya Mountains ; and of 
these some visit the plains of India, and extend their range eastward to Japan. In America there are two, 
which are found in all parts of that country from the United States to Mexico. 
Genus Certhia. 
114. Certhia pamiliaris Vol. II. PI. LXIV. 
Tree-creeper. 
A resident species, generally distributed over the three kingdoms, and braving with apparent impunity 
the coldest of our winters. 
Genus Phyllopneuste. 
The trivial name of Leaf- Warblers has of late years been applied to the members of this genus, a term 
which I regret not having employed in the body of the work. These delicate birds are so generally dispersed 
over the northern and temperate countries of the Old World that they may be regarded as universally diffused. 
They are all more or less migratory, moving backward and forward in accordance with the course of the 
sun. Three species arrive in Britain early in the spring.
