_Description._--Above reddish brown; head blackish; sides of head pale cinereous: beneath chestnut-brown; chin pale cinereous; lower half of abdomen pale ochraceous, distinctly barred with undulating black bands; bill brown, yellowish at the base; feet dark flesh-colour: whole length 12·0 inches, wing 6·2, tail 1·8. _Hab._ Southern Brazil, Paraguay, and Northern Argentina. White refers a Tinamou which he shot at Oran in November 1880 to _Crypturus cinereus_. There can be little doubt, however, that the specimen in question really belonged to the allied species _C. obsoletus_, which is known to occur in Paraguay. The true _C. cinereus_ is from a much more northern locality, and is not likely to be found in Argentina. 426. CRYPTURUS TATAUPA (Temm.). (TATAUPA TINAMOU.) +Crypturus tataupa+, _Scl. et Salv. Nomencl._ p. 152; _Salvin, Ibis_, 1880, p. 364 (Salta); _White, P. Z. S._ 1882, p. 629, (Oran). +Ynambū tatāupā+, _Azara, Apunt._ iii. p. 48. _Description._--Above chestnut-brown; head and neck dark cinereous: beneath cinereous; throat white; middle of belly white; flanks and crissum varied with undulating bars of black and white; bill yellowish; feet dark ashy: whole length 10·0 inches, wing 5·2, tail 1·8. _Female_ similar. _Hab._ South Brazil, Paraguay, and Northern Argentina. The Tataupa Tinamou was first described by Azara as an inhabitant of Paraguay, whence it extends into the northern provinces of the Argentine Republic. White obtained specimens among the undergrowth in the dense forests of Campo Colorado, near Oran, and Durnford also met with it near Salta. To Azara's interesting account of the Tataupa's habits nothing has been recently added. He says that this species inhabits woods and thickets, and also approaches houses where it finds cover--hence the Guarani name, which means a bird of the house. It lays four eggs of a fine purple colour; and when driven from the nest flutters along the ground, feigning lameness. It sings all the year round, and for power and brilliance of voice is preeminent among this class of birds. After the first note of its curious song there is an interval of eight seconds of silence; then the note is repeated with shorter and shorter intervals, until, becoming hurried, they run into a trill, followed by a sound which may be written _chororó_, repeated three or four times. When sitting close it tips forward, pressing its breast on its legs, so that the rump is raised higher than the back, and opening the terminal feathers of the body, it spreads them in a semicircle over the back as if to conceal itself beneath them, and when looked at from behind nothing is visible except this fan of feathers. The feathers are concave with points inclining upward, and when thus disposed have a strange and beautiful appearance. 427. RHYNCHOTUS RUFESCENS (Temm.). (GREAT TINAMOU.)
