So great a similarity reigns throughout the _Podargi_ inhabiting Australia, that it is most difficult to distinguish them; and after a minute examination of a great number of specimens it appears to me that there are five species, only two of which are inhabitants of New South Wales, and to these, in my opinion, the various names of the older authors are referrible. But as it must ever remain a matter of uncertainty as to which these names have been applied, I have preferred to retain for the present bird that proposed by Messrs. Vigors and Horsfield.
