Galapagos Archipelago. Frequents the sea-coast and salt-lagoons. There are no fresh water pools in any of these islands. 1. NYCTICORAX VIOLACEUS. _Bonap._ Ardea violacea, _Linn._ Ardea callocephala, _Wagl._ Syst. Av. Mr. G. R. Gray has thought it advisable to give the following description of this specimen, from the Gallapagos Archipelago. It appears to be a young bird, and is small in all its dimensions. Upper part blackish grey; each feather marked down the middle with a broad stripe of black, and tinged on the margins with shining bronze brown; beneath the body blueish grey, with the front of the neck, top of the head, and margins of the feathers on the thighs rufous; the sides of the head and throat deep black, the former divided in the middle on each side with a patch of white; the bill black, and feet of a pale reddish colour. 2. NYCTICORAX AMERICANUS. _Bonap._ Ardea nycticorax, _Wils._ (young bird.) Valparaiso, Chile. THERISTICUS MELANOPS. _Wagl._ Ibis melanops, _Lath._ Hist. ix. pl. 150. This bird frequents the desert gravelly plains of Patagonia, as far south as lat. 48°: in the British Museum there are specimens which Captain Clapperton brought from central Africa; so that this bird has an extraordinarily wide range. It generally lives in pairs, but during part of the year in small flocks. Its cry is very singular and loud: when it is heard at a distance it closely resembles the neighing of the guanaco. I opened the stomach of two specimens, and found in them remains of lizards, cicadæ, and scorpions. It builds in rocky cliffs on the sea shore: egg dirty white, freckled with pale reddish brown; its circumference over longer axis is seven inches. The legs are carmine and scarlet-red: iris scarlet-red. IBIS (FALCINELLUS) ORDI. _Bonap._ Tantalus Mexicanus, _Ord._ Journ. Acad. Phil. Tantalus chalcopterus? _Temm._ Ibis Falcinellus, _Bonap._ Am. Orn. iii. My specimen was obtained at the Rio Negro: it is very numerous in large flocks on the vast swampy plains between Bahia Blanca and Buenos Ayres. Its flight when soaring is singularly graceful; the whole flock moving in precise concert. 1. NUMENIUS HUDSONICUS. _Lath._ Numenius Hudsonicus, _Lath._ Ind. Orn. ii. 712. This curlew is very abundant on the tidal mud-banks of Chiloe. When the flock rises, each bird utters a shrill note. 2. NUMENIUS BREVIROSTRIS. _Licht._ Numenius brevirostris, _Licht._ Cat. 75, sp. 774 a. Buenos Ayres. LIMOSA HUDSONICA. _Swains._ Scolopax Hudsonica, _Lath._ Ind. Orn. ii. 720. My specimens were obtained from the Falkland Islands and from Chiloe, where it frequented the tidal mud-banks in flocks.
