by the indentations around the edge.

_d_, the principal decoration here is the plumed serpent with a
bird's head.

_e_, a vase in the shape of a duck.

_f_, a bowl decorated only around the edge and in the interior.

PLATE II

Height, 16.5 cm.

Here is shown what, in regard both to manufacture and to decoration,
is the best specimen in the collection. Its principal ornaments are the
plumed serpent and two birds, all clearly seen in the extension of the
design above and below the vase. The lower section is a continuation
of the upper one.

The birds are represented as in flight. Mr. M. H. Saville is
probably right in considering them as quetzals, though the habitat
of this famous trogon is Central America and the southernmost part
of Mexico. The bird and the serpent form the decoration of other
jars of this collection and would indicate that the makers of this
pottery were affiliated with the Aztecs in their adoration of the
great deity Quetzalcoatl.
