_Description._--Above cinereous; feathers of head and back marked

with narrow black and fulvous cross bands and margined with bright

ashy-white edgings; wings ashy black, crossed on both webs by

fulvous bands, except in the two outer primaries: beneath pale

fulvous, throat white; breast more cinereous, and densely covered

with indistinct black and brown cross bars and whitish-grey streaks;

flanks and lower belly with irregular black cross bars; bill

horn-colour; lower mandible and feet yellowish: whole length 8·5

inches, wing 5·4, tail 2·4.

_Hab._ Northern Patagonia.

This species, called _Perdiz chico_ by the natives, is somewhat smaller

and paler in colouring than the common Tinamou of the pampas, but very

closely resembles the young of that species. It inhabits Patagonia,

and is nowhere very numerous, but appears to be thinly and equally

distributed on the dry sterile plains of that region, preferring places

abounding in thin scrub. In disposition it is extremely shy, and when

approached springs up at a distance ahead and runs away with the

greatest speed and apparently much terrified. Sometimes when thus

running it utters short whistled notes like the allied species. It rises

more readily and with less noise than the pampas bird, and has a much

higher flight. It has one call-note, heard only in the love-season--a

succession of short whistling notes, like those of the _N. maculosa_,

but without the rapidly uttered conclusion.

The nest is made under a small scrubby bush, and contains from five to

seven eggs, in form and colour like those of _N. maculosa_, except that

the reddish-purple tint is paler.

The figure (Plate XX.) is taken from one of my specimens from the Rio

Negro, now in the British Museum.
