Genus ARDEA

Bill long, compressed, pointed; culmen nearly straight; both mandibles slightly serrated at commissure, upper mandible grooved on each side of culmen; nostrils subbasal, elongate, situated in the groove. Sides of head to behind the eyes naked. Tarsus long, scutellate in front; tibia half-naked. Wings ample; tail short. Upper surface grey ; the feathers at the base of the neck and the scapulars elongate, forming ornamental plumes ; no dorsal train. Head crested.

This genus is almost cosmopolitan; of the ten species known half occur in India. The Purple Herons, which have a proportionally larger foot and differ slightly in habits, are placed by Sharpe in a distinct genus, Phoyx, but the division, though justifiable, appears scarcely necessary.
