neighbourhood of Concepcion, lat. 37°, to south of the Peninsula of Tres Montes, 
between 41° and 50°. It is not found in Tierra del Fuego, where the climate pro- 
bably is too cold for it, for in other respects, the great forests of that country 
appear admirably adapted to its habits. Its limit, northward of the province of 
Concepcion, is evidently due to the change which there takes place, from dense 
forests to an open and dry country. The P. Tarnii is abundant in all parts of the 
Island of Chiloe, where it is called by the native Indians, guid-guid; but by the 
English sailors, the barking-bird. This latter name is very well applied, for the 
noise which it utters is precisely like the yelping of a small dog. When a person 
is walking along a pathway within the forest, or on the sea-beach, he will often be 
surprised to hear on a sudden, close by him, the barking of the guid-guid. He 
may often watch in vain the thicket, whence the sound proceeds, in hopes of see- 
ing its author, and if he endeavour, by beating the bushes, to drive it out, his 
chance of success will be still smaller. At other times, by standing quietly within 
the forest, the guid-guid will fearlessly hop close to him, and will stand on the 
trunk of some dead tree, with its tail erect, and strange figure full in view. It 
feeds exclusively on the ground, in the thickest and most entangled parts of the 
forest. It rarely takes wing, and then only for short distances. It has the power 
of hopping quickly and with great vigour ; when thus awkwardly proceeding, it 
carries its short tail in a nearly erect position. I was informed that the guid-guid, 
builds a nest amongst rotten sticks, close to the ground.

This bird is common in the dry country of central and northern Chile, where 
it replaces the P. Tarnii of the thickly wooded southern regions. The P. mega- 
podius, is called by the Chilenos, “ EL Turco it lives on the ground amongst 
the bushes which are sparingly scattered over the stony hills. With its tail erect, 
every now and then it may be seen popping on its stilt-like legs from one bush to 
another with uncommon celerity. Its appearance is very strange and almost ludi- 
crous, and the bird seems always anxious to hide itself. It does not run, but hops, 
and can hardly be compelled to take flight. The various loud cries which it utters, 
when concealed in the bushes, are as strange as its appearance. I opened the ex- 
tremely muscular gizzards of several of these birds, and found them filled with 
beetles, vegetable fibres, and pebbles. Observing the structure of the gizzard, the
