The bird has a very wide range in South America, and Mr. Salmon observed its breeding-habits in Antioquia in Colombia. There also the bird varies the form of its nest, making it as large as that of an English Magpie, and roofing the top with a mass of large leaves to protect it from the heavy rains. The eggs, he says, are very pale greenish blue, nearly white; but he does not give the number. 195. SYNALLAXIS WHITII, Scl. (WHITE'S SPINE-TAIL.) +Synallaxis whitii+, _Scl. Ibis_, 1881, p. 600, pl. xvii. fig. 2; _White, P. Z. S._ 1882, p. 611 (Salta). _Description._--Above dark brown, lores, and superciliaries white; wings and tail chestnut red; beneath cinnamomeous, paler on the middle of the belly; large spot in the middle of the throat black; inner margins of wing-feathers and under wing-coverts cinnamomeous; bill black, feet pale hazel: whole length 5·7 inches, wing 2·5, tail 2·6. _Hab._ Northern Argentina. White obtained a single example of this new species near Oran in November 1880. It is most nearly allied to _S. scutata_ of Brazil. 196. SYNALLAXIS PHRYGANOPHILA (Vieill.). (PRETTY-THROATED SPINE-TAIL.) +Synallaxis phryganophila+, _Burm. La-Plata Reise_, ii. p. 409 (Paraná); _Scl. et Salv. Nomencl._ p. 64; _Scl. P. Z. S._ 1874, p. 17; _White, P. Z. S._ 1882, p. 611 (Buenos Ayres); _Barrows, Bull. Nutt. Orn. Cl._ viii. p. 207 (Entrerios). _Description._--Above, front brown, crown chestnut, superciliaries white; sides of head, neck, back, and tail pale fulvous brown, with broad blackish striations on the neck and back; upper wing-coverts pale chestnut; wing-feathers blackish, the outer webs edged with pale fulvous brown; beneath, upper half of throat sulphur-yellow, lower half black, with a white patch on each side of the black; breast and belly whitish, washed with earthy brown, slightly fulvous on the breast and flanks; under wing-coverts fulvous white; bill and feet horn-colour: whole length 8·5 inches, wing 2·4, tail 4·6. _Hab._ Paraguay, Argentina, and Uruguay. This pretty Spine-tail is nowhere common in the Argentine country, and in Buenos Ayres it is exceedingly scarce. It is rather large for a _Synallaxis_, the total length being nine inches. The two middle feathers of the acuminated tail greatly exceed the others in length, measuring five inches. The plumage is very pale brown, marked with fuscous; the crown and wing-coverts rufous. The beauty of the bird is in the throat, which has three strongly contrasted colours, distinguishing it from all other _Synallaxes_. In the angle of the beak the colour is sulphur-yellow, under this is a patch of velvet-black, and on each side of the yellow and black a pure white patch.
