Genus ACANTHIZA, _Vig. & Horsf._ With the exception of the north coast, the _Acanthizæ_ 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 _Acanthizæ_ 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. chrysorrhœa_, _A. Reguloïdes_, &c., 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 (_Chrysococcyx lucidus_). 206. Acanthiza pusilla Vol. II. Pl. 53. 207.

Genus EPHTHIANURA, _Gould_. _Bill_ shorter than the head, nearly straight, compressed laterally, notched at the tip, gonys incurved; _nostrils_ basal, linear, and covered by a membrane; _wings_ long, first quill spurious, second very long, third and fourth equal and longest; _tertials_ very long; _tail_ short and truncate; _tarsi_ entire, moderately long, slight; _toes_ slender, the hinder toe and claw shorter than the middle one, the inner toe rather shorter than the outer.
