The native name of this bird, which we have adopted as its 

 specific name, is Berigora. It is called by the settlers Orange- 

 speckled Hawk. Mr. Caley informs us, that the orange marks 

 in the plumage of this species are considerably stronsjer in 

 recent specimens than in those of the Society's collection, which

 but that bird is described as having a double tooth to its bill, 

 while ours is singly-toothed as in the genuine Falcons.
