Habitat, Galapagos Archipelago (_October_). This species appear quite distinct from any described one. HIMANTOPUS NIGRICOLLIS. _Vieill._ Himantopus nigricollis, _Vieill._ Ency. Meth. 340. Recurvirostra himantopus, _Wils._ Am. Orn. pl. 58. f. 2. My specimens were obtained from the provinces bordering the Plata. On the great swampy plains and fens which lie between Buenos Ayres and Bahia Blanca, it is very numerous in small, and occasionally, in large flocks. This plover, which appears as if mounted on stilts, has been wrongfully accused of inelegance; when wading about in shallow water, which is its favourite resort, its gait is far from awkward. In a flock it utters a noise, which singularly resembles the cry of a pack of small dogs in full chase: when I travelled across the above mentioned plains, I was more than once startled, when lying awake at night, at the distant sound, and thought the wild Indians were coming.
