_Description._--Above bronzy brown; top of head cinereous: beneath
more ochraceous; throat and breast washed with bronzy; neck and
breast slightly spotted with greyish; under wing-coverts, flanks,
and crissum chestnut; tail bronzy green, five outer rectrices
broadly tipped with chestnut; bill yellowish; feet pale hazel: whole
length 22·0 inches, wing 9·8, tail 10·3. _Female_ similar.
_Hab._ Paraguay and Northern Argentina.
For our first knowledge of this Guan we are also indebted to Azara, who
described it in his 'Apuntamientos' (iii. p. 77) under the name _Yacú
caraguata_, as found in the forests of Paraguay. Thence it extends
into the wooded districts of the northern provinces of the Argentine
Republic, where it was obtained by Dr. Burmeister in Tucuman and by
Capt. Page's expedition on the Rio Paraná and Rio Vermejo. It is
probable also that the Guan met with by White near Salta, and referred
by him to _O. guttata_, was really of the present species.
Order XIV. GERANOMORPHÆ.
Fam. XLIII. RALLIDÆ, or RAILS.
The Rallidæ are well represented in the Argentine Republic, eight Rails
and Crakes, two Waterhens, and three Coots being met with within
its limits, and it is highly probable that the list will be further
augmented as discovery advances.
The presence of three species of Coots, all apparently in abundance, is
a somewhat special peculiarity of the Argentine Ornis. Most of the other
Argentine Rallidæ have an extended range.
