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 stronger in 
recent specimens than in those of the Society's collection, which 
are much faded. The specific characters of this bird accord 
very closely with those of Dr. Latham's ** Cream-bellied Falcon* ;" 
but that bird is described as having a double tooth to its bill, 
while ours is singly-toothed as in the genuine Falcons.
