Ovalau: Layard (the only form recorded by Ogilvie- Grant--possibly this is the same basis as the Ovalau record under the preceding species.) Falconidae. Falcons. Falco melanogenys Gould.

Falco lunatus Daudin is preoccupied by F. lunulatus Latham, or vice versa, and this may be a form of F. peregrinus, the well known Peregrine falcon, or one of its Australian subspecies.
