Their habits lead them to frequent the most retired parts of the forests, damp and secluded places and ae gullies where the herbage is thick and dense; but some species are found on the flat islands near the coast, covered with Salsole 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 Mo flight is peculiar and never protracted, and they all build domed nests like that of the common Wren ( Troglodytes Europeus). 199.

Subfamily E Genus Acanruiza, /2g. § Horsf. With the exception of the north coast, the Acanthize 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 Acanthize 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. chrysorrhwa, A. Reguloides, &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 (Chryso- coccyx lucidus). 206. Acanthiza pusilla Vol. WP Rios: 207.
