birds or flying animals.

A more highly conventionalized figure of a bird than any thus far
described is painted on the food bowl reproduced in plate CXL, _b_.
The head is represented by a terraced figure similar to those which
appear as decorations on some of the other vessels; the wings are
simply extended crescents, the tips of which are connected by a band
which encircles the body and tail; the body is continued at the
posterior end into two triangular appendages, between which is a tail,
the feathers of which are not differentiated. On each side of the
body, in the space inclosed by the band connecting the tips of the
wings, a figure of a dragon-fly appears.

The figure on the food bowl illustrated in plate CXXXIX, _c_, may also
be reduced to a conventionalized bird symbol. The two pointed objects
on the lower rim represent tail-feathers, and the triangular
appendages, one on each side above them, the body, as in the designs
which have already been described. Above the triangles is a
rectangular figure with terraced rain-cloud emblems, a constant
feature on the body and head of the bird, and on each side, near the
rim of the bowl, occur the primary feathers of the wings. The cross,
so frequently associated with designs representing birds, is replaced
by the triple intersecting lines in the remaining area. The
resemblance of this figure to those already considered is clearly
evident after a little study.

The decoration on the food basin presented in plate CXXXIX, _a_, is
interesting in the study of the evolution of bird designs into
conventional forms. In this figure those parts which are identified as
homologues of the wings extend wholly across the interior of the food
bowl, and have the forms of triangles with smaller triangular spurs at
their bases. The wings are extended at right angles to the axis of the
body, and taper uniformly to the rim of the bowl. The smaller spurs
near the union of the wings and body represent the posterior part of
the latter, and between them are the tail-feathers, their number being
indicated by three triangles.

There is no representation of a head, although the terraced rain-cloud
figure is drawn on the anterior of the body between the wings.

The reduction of the triangular wings of the last figure to a simple
band drawn diametrically across the inner surface of the bowl is
accomplished in the design shown in plate CXXXIX, _b_. At intervals
along this line there are arranged
