This representative of the golden plover of Europe and North America, is common on the banks of the Plata in large and small flocks. It is found also, according to Meyer, in Chile. 1.

I obtained specimens of this bird in Tierra del Fuego, where it inhabited both the sea shore and the bare stony summits of the mountains; at the Falkland Islands, where it frequented the upland marshes; and at Chiloe, where I met with large flocks in the fields, not near the coast. 2. SQUATAROLA FUSCA. _Gould._ _S. vertice corporeque supra fuscis, dorsi parapterique plumis pallidiore marginatis; remigibus primariis nigrescenti fuscis, pogoniis externis albo angustè marginatis rhachibus albis; uropygio caudâque obscurè fuscis, remigibus externis albo latè marginatis et terminatis; fronte, genis, gulâ, abdomine postico, caudæeque tegminibus inferioribus flavescenti albis, colli pectorisque lateribus fuscis, colli plumis fusco pallido terminatis; pedibus nigris._ Long. tot. 8 unc.; _alæ_, 5⅝; _caudæ_, 3; _tarsi_, 1⅜; _rostri_, ⅞. Crown of the head, all the upper surface brown, the feathers of the back and the scapularies, margined with paler; primaries blackish brown, finely edged on their inner margins with white, and with white shafts; rump and tail dark brown, the outer feathers largely margined and tipped with white; forehead and sides of the face sandy white; throat, lower part of the abdomen, and under tail coverts, buffy white; sides of the neck and chest brown; the feathers of the latter tipped with still lighter brown; bill and feet black. Habitat, Maldonado; inland grassy plains. This species is most closely allied to the foregoing. I obtained only one specimen, which, on comparison with several of the _S. cincta_, appears a little larger in all its dimensions, especially in the length of the tarsi. Its back and scapularies are of a more uniform brown, the feathers being less edged with pale brown. Its feet are black, whereas those of _S. cincta_ are brown. PHILOMACHUS CAYANUS. _G. R.
