After the first moulting the young attain the streaming shoulder-feathers, but only exhibit the bare head and neck in their third year. This species is from twenty-eight to twenty-nine inches long, and fifty-one broad; the wing measures from thirteen to fourteen, and the tail six inches. This bird has been the subject of many strange tales from the most remote times, and is called the Sacred Ibis because it figures extensively, and evidently in a religious character, on the hieroglyphics of ancient Egypt. It is not improbable that the estimation in which it was held arose from the fact that its annual appearance was coincident with the rising of the Nile, a phenomenon on which depends the prosperity of the whole country. According to our own observations, this species is now but rarely seen in Egypt, and was never met with by us below eighteen degrees north latitude; it, however, occurs regularly in South Nubia and the Soudan, where it arrives at the beginning of the rainy season, and after having reared its young, migrates, or wanders over the country to a considerable distance. In India it is not uncommon during the cold season.

This Ibis was formerly supposed to destroy and eat snakes, and the supposition appeared corroborated by the fact that
