Nothing resembling the toucan, as has been seen, has been found in the
mounds; but, as stated, this bird is found in Southern Mexico.

The buzzard is to-day common over almost the entire United States, and
is especially common throughout most of the Mississippi Valley.

As to the paroquet, there seems to be no evidence in the way of carvings
to show that it was known to the Mound-Builders, although that such was
the case is rendered highly probable from the fact that it lived at
their very doors.

It therefore appears that of the five animals of which Wilson states
"the majority are not known in the United States," and "some of them are
totally unknown, within any part of the North American continent," every
one is found in North America, and all but one within the limits of the
United States, while three were common residents of the Mississippi
Valley.

As a further illustration of the inaccurate zoological knowledge to
which may be ascribed no small share of the theories advanced respecting
the origin of the Mound-Builders, the following illustration may be
taken from Wilson, this author, however, being but one of the many who
are equally in fault. The error is in regard to the habitat of the conch
shell, _Pyrula (now Busycon) perversa_.

After exposing the blunder of Mr. John Delafield, who describes this
shell as unknown on the coasts of North and South America, but as
abundant on the coast of Hindostan, from which supposed fact, coupled
with its presence in the mounds, he assumes a migration on the part of
the Mound-Builders from Southern Asia (Prehistoric Man, vol. 1, p. 219,
