_Hab._ South Brazil and Argentina.

White obtained examples of this species on the Sierra of Totoral. He says it is a very wild bird and exceedingly scarce.

_Description._--Above olivaceous brown; head blackish, thickly covered with yellowish-buff elongated shaft-spots; rump and upper tail-coverts tinged with chestnut; wing-feathers chestnut, tinged with olivaceous; tail chestnut; beneath pale earthy olive-brown, paler on the throat, the shafts of the feathers of the breast buffy white, forming long lines, the feathers of the belly and under tail-coverts transversely barred with blackish; under wing-coverts yellowish white, spotted with blackish; bill and feet black: whole length 105 inches, wing 47, tail 46. _Female_ similar.

_Hab._ Brazil and Northern Argentina.

White obtained specimens of this species at Concepcion, "in the thickest parts of the woods, near the river, climbing up the trees, around which it turned in corkscrew fashion."

218. DRYMORNIS BRIDGESI, Eyton.

(BRIDGES'S WOOD-HEWER.)

[Plate X.]

[Ill.u.s.tration: DRYMORNIS BRIDGESI.]

+Drymornis bridgesi+, _Scl. et Salv. Nomencl._ p. 67; _White, P.

Z. S._ 1882, p. 613 (Catamarca); _Barrows, Auk_, 1884, p. 20 (Entrerios). +Nasica gracilirostris+, _Burm. La-Plata Reise_, ii.

p. 466 (Rio Quinto).

_Description._--Above and below brown, brightest on the rump, and palest beneath; long superciliaries extending down the neck, and a mystacal stripe formed of white spots with faint black edgings; wing-feathers blackish; tail chestnut; on the throat a broad white band extending to the breast; breast and belly marked with large oblong white spots, which are margined with narrow black edgings; under wing-coverts and inner margins of secondaries bright cinnamon; bill and feet horn-colour: whole length 1210 inches, wing 56, tail 46. _Female_ similar.

_Hab._ North and West Argentina.

Eyton, when he described this species from Bridges's specimens, gave its habitat as Bolivia. It may inhabit the southern part of that Republic, but it is more probable that Bridges's examples were obtained in Northern Argentina, which he likewise visited. Bridges's Wood-hewer is the only member of its genus, and is one of the largest of the whole family _Dendrocolaptidae_, measuring some 13 or 14 inches in length, inclusive of the great curved beak. Although found throughout the northern portion of the Argentine Republic, its habits are as yet imperfectly known, but the following extracts show that they must be very interesting, and that the bird is remarkably versatile. Mr. Barrows writes:--"These birds are somewhat gregarious, being oftenest seen in small parties of six to ten. They sometimes cling against the bark of a tree in the manner of Woodp.e.c.k.e.rs, but also spend much of their time on the ground. I think they use their curved bill much oftener for probing in the ground than for searching the bark of trees, as many of those shot had the base of the bill and the frontal feathers plastered with mud. In the stomach of the first one killed I found the silken sac, three fourths of an inch in diameter, or the eggs of a large spider, which makes holes ten or twelve inches deep in the hard soil everywhere."

White obtained examples of this species at Catamarca, and also notices its strangely contrasted habits. He writes:--"The cry of this bird is much the same as that of a Woodp.e.c.k.e.r, and it clings to the algarroba trees in a similar way; but in the afternoon it is seen scattered about on the sandy ground in the pursuit of insects."

219. XIPHOCOLAPTES ALBICOLLIS (Vieill.).

(WHITE-THROATED WOOD-HEWER.)

+Xiphocolaptes albicollis+, _Scl. et Salv. Nomencl._ p. 68; _White, P. Z. S._ 1882, p. 613 (Misiones).

_Description._--Above, head black, with clear whitish-yellow shaft-spots; lores and long superciliaries white; neck, back, and upper wing-coverts olive-brown; rump and upper tail-coverts washed with bright chestnut; wing-feathers dark chestnut, the outer webs glossed with olivaceous; tail chestnut; beneath pale olive-brown, buffy white on the throat and with similar shaft-spots on the breast; feathers of the belly and under tail-coverts transversely barred with black; under wing-coverts cinnamomeous yellow barred with black; bill and feet black: whole length 120 inches, wing 54, tail 48. _Female_ similar.

_Hab._ Brazil and N. Argentina.

White obtained examples of this large Wood-hewer in Misiones.

220. XIPHOCOLAPTES MAJOR (Vieill.).

(CHESTNUT WOOD-HEWER.)

+Xiphocolaptes major+, _Scl. et Salv. Nomencl._ p. 68; _White, P. Z.

S._ 1882, p. 613 (Salta); _Durnford, Ibis_, 1880, p. 359 (Tuc.u.man).

_Description._--Above and below nearly uniform chestnut, tinged with olivaceous on the crown and throat; narrow shaft-spots on the breast-feathers whitish, forming faint lines; beak pale horn-colour; feet bluish grey: whole length 1110 inches, wing 55, tail 40.

_Female_ similar.

_Hab._ North Argentina, Paraguay, and Bolivia.

This large and powerful Wood-hewer is confined to the hottest portion of the Argentine Republic, and also inhabits Paraguay and Bolivia. White met with it at Oran, in the province of Salta, and writes concerning its habits:--"Common here in the dense forest, where their continued hard pecking at the lofty tree-trunks is very accentuated. Two or three at a time maintain a continued race up a magnificent clear stem as far as the branches, when they fly to the bottom of the next and do likewise."

This species is nearly a foot in length, the beak being about two inches long, curved and very powerful. The tail is stiff, being used as a support in climbing, and the claws are strong and sharply hooked. The colour of the whole plumage is nearly uniformly bright rufous.
