p. 440; _Withington, Ibis_, 1888, p. 473.
_Description._--Above dirty brown, varied with blackish; wings
cinereous with white tips to some of the secondaries: beneath white,
sprinkled with greyish on the breast and sides; chin and throat
black; bill short, compressed, plumbeous, crossed by a black band;
feet black: whole length 12·0 inches, wing 5·0, tail 1·0. _Female_
similar.
_Hab._ North and South America.
The Thick-billed Grebe extends all through America, from Canada down
to Patagonia and Chili. It does not seem to have been noticed in the
Argentine Republic except by Mr. Withington, who sends us a single
specimen from the Lomas de Zamora, near Buenos Ayres.
A second and larger species of this genus (_P. antarcticus_) occurs on
the western side of America from Guatemala to Chili.
Order XVIII. IMPENNES.
Fam. LII. APTENODYTIDÆ, or PENGUINS.
The Penguins are a peculiar group of oceanic birds which differ
essentially from all other birds in the construction of their wings and
feet, and should certainly form an Order apart. They are denizens of the
Antarctic sea-shores and islands, but in the Pacific go as far north as
the Galapagos. On the shores and islands of South America nine species
occur, one of which has been met with within our limits.
