"Falcons. Bill furnished with a sharp tooth and notch near the end of the cutting edge of the upper mandible (sometimes two such teeth), and the end of under mandible truncated, with notch near the tip. Nostrils circular, high in the cere, with a prominent central tubercle. Inter-nasal septum extensively ossified. Palate with a median keel anteriorly. Superciliary shied prominent, in one large piece. Shoulder-joint strengthened by union of scapular process of the coracoid with the clavicle as in Micrastur, Herpetothers, and the Polyborinae alone of Flaconidae. Wings strong, long, and pointed, with rigid and usually straight and tapering flight-feathers; the tip formed by the 2d and 3d quills, supported nearly to their ends by the 1st and the 4th, both of which are longer then the 5th; only one or two outer primaries emarginate on inner webs near the end. Tail short and stiff, with more or less tapering rectrices. Feet strong, rather short, the tarsus of less length than the tibia, feathered more or less extensively, elsewhere irregularly reculate in small pattern varying with the genera or subgenera; never scutellate in single series before or behind. Middle toe very long; talons very short." Elliot Coues, 1884
