Genus Sriprrurus, Less. 
A form confined to Australia. Although some slight variation occurs in the specimens from Van Diemen’s 
Land, Southern and Western Australia, I believe that they are all referable to one and the same species, viz.—

Genus Dasyornis, 7g. & Horsf. 
A group of birds adapted for situations covered with an almost impenetrable vegetation, reed-beds, &c. The 
two species figured are all that are at present known; of these one is from the eastern and the other from the 
western parts of Australia.

Prior to my visit to Australia, I described a bird in the ‘ Proceedings of the Zoological Society,’ Part V. 
p. 150, as D.? brunneus, but as I have not since met with the bird in any collection from Australia I presume it is 
not a native of that country. 
Genus Arricuia, Gould. 
Rictus totally devoid of bristles; bi// as long as the head, compressed laterally; the upper mandible distinctly 
notched at the tip ; gonys ascending from the rictus and then following the line of the bill; ew/men ascending high in 
front ; nostrils moderately large, covered with an operculum, and placed in a groove near the base of the bill; wings 
short, round, concave, the first three primaries graduated, the fourth, fifth, sixth and seventh equal; tail lengthened, 
rounded, the stems rigid, the webs loose and decomposed ; tarsi and feet robust, the hind-toe armed with a strong 
nail; outer and inner toes equal in length. 
The only species of this genus yet discovered is as singular in its structure as it is shy and retiring in its 
habits ; the total absence of vibrisse in a bird apparently closely allied to Dasyornis, in which they are so much 
developed, renders it one of the anomalies of the Australian fauna.

Genus Spuenaacus, Strick. 
A group of reed- and grass-frequenting birds, which are found not only in every part of Australia, but also in 
the Indian Islands and India.
