INTRODUCTION. 
fifth and sixth nearly equal and the longest ; tail moderate and square ; tarsi long ; hind-toe and claw strong, and 
nearly equal to the middle toe and claw in length ; outer and inner toes equal ; plumage soft and silky to the touch. 
A group of small birds peculiar to Australia, and confined almost exclusively to the southern portion of the 
country. Their habits lead them to frequent the most retired parts of the forests, damp and secluded places and 
scrubby gullies where the hei'bage is thick and dense ; but some species are found on the flat islands near the coast, 
covered with Salsolai and other shrub-like trees ; they usually frequent the ground, over which they pass with 
celerity, and when their haunts are intruded upon conceal themselves under the fallen or dried herbage. Their 
flight is peculiar and never protracted, and they all build domed nests like that of the common Wren (^Troglodytes 
Europceus^.

Subfamily 
Genus Acanthiza, F^i^'. Sf Horsf. 
With the exception of the north coast, the Acanthizce are dispersed over all the wooded districts of Australia 
and Van Diemen's Land ; some species frequenting the brushes, while others tenant the shrubs and belts of trees 
on the plains ; others again are only found in such districts as the belts of the Murray. 
Like some other large groups at present included under one generic title, the Acanthizce might be divided with 
propriety ; thus the A. pusilla, A. Diemenensis, &c., which are feeble in structure and strictly arboreal, might form 
one section ; while the A. chrysorrhcea, A. Reguloides, Sec, which resort to the ground, might form another. The 
nests of all the species that I have seen are of a domed form like that of the European Wren. 
The members of this genus and the Maluri are frequently the foster-parents of the shining Cuckoo (Chryso- 
coccyx lucidus^.
