This form is peculiar to Australia, in every portion of which great country, including Van Diemen’s Land, one or other of the species I have figured are to be found; some of them associated in the same district, and even inhabiting the same trees, while in other parts only a single species exists; for instance, the _P. punctatus_, _P. quadragintus_ and _P. affinis_ inhabit Van Diemen’s Land; on the whole of the southern coast of the continent from east to west _P. punctatus_ and _P. striatus_ are associated; the north coast is the cradle of the species I have called _P. uropygialis_, and the east coast that of _P. melanocephalus_, from both of which countries the others are excluded; the true habitat of the beautiful species I have figured and described as _P. rubricatus_ is not yet known. The seven species of this little group are each individually very numerous, which, together with their general distribution, may enable them to effect some important operation in the economy of nature; their chief food consisting of the larvæ of insects. 76.

Family LANIADÆ, _Vig._ Genus STREPERA, _Less._ Prior to the commencement of the present work only two species of this form (_S. graculina_ and _S. Anaphonensis_) had been described, and these had been referred to a different genus by almost every author who had occasion to mention them; the older writers assigning them to _Corvus_, _Coracias_ and _Gracula_, and the more modern ones to _Cracticus_ and _Barita_: finding that their structure did not agree with the character of either of those genera, I (in 1837) proposed to make the first-mentioned species the type of a new genus (_Coronica_), not being aware at the time that this had been done some years before by M. Lesson, whose name, having the priority, is necessarily the one adopted.
