(1) It is probable that the genus Ieracidea of Gould, will only prove 
to be an aberrant, or subgeneric form, of the restricted genus Falco, or of 
the same value as the group of the Kestrils, which, by some, have 
been separated from Falco. 
(2) A second species of this genus is given in Gould’s “ Synopsis of 
the Birds of Australia,” under the title of Lepulogenys subcristatus , 
Lepidogenys having been substituted for Lophotes , as that term had 
been previously employed. 
(3) Whether this group, of which F. Pondecerianus Auct. is a type, be- 
longs to this subfam., or to the Pandions (Ospreys), seems a matter of 
doubt. I have substituted the title of Haliastur for that of Halicettus, 
given it by Mr. Swainson, as the latter already designates a group 
of the Eagles. To it will belong the Halicettus leucosternns and 
Halicettus canorus of “ Gould’s Syn. of the Birds of Australia.”
