ey pattern. One
side of these triangles is continued into a line from which hang two
breath feathers, while the other end of the same line ends in a round
dot with four radiating, straight lines. The triangles recall the
butterfly symbol, the key pattern representing the head.

In figure 326 there is a still more aberrant form of the W-shape
design. The wings are folded, ending in triangles, and prolonged at
their angles into projections to which are appended round dots with
three parallel lines. The median portion, or that in the reentrant
angle of the W, is a four-sided figure in which the triangle
predominates with notched edges. Figure 327 shows the same design with
the median portion replaced by a rectangle, and in which the key
pattern has wholly disappeared from the wings. In figure 328 there are
still greater modifications, but the symmetry about a median axis
remains. The ends of the wings instead of being folded are expanded,
and the three triangles formerly inclosed are now free and extended.
The simple median rectangle is ornamented with a terrace pattern on
its lower angles.

Figure 329 shows a design in which the extended triangles are even
more regular and simple, with triangular terraced figures on their
inner edge. The median figure is a triangle instead of a rectangle.

[Illustration: FIG. 331--Double rectangle; median rectangle]

Figure 330 shows the same design with modification in the position of
the median figure, and a slight curvature in two of its sides.

Somewhat similar designs, readily reduced to the same type as the last
three or four which have been mentioned, are shown in figures 331 and
332. The resemblances are so close that I need not refer to them in
detail. The W form is wholly lost, and there is no resemblance to a
bird, even in its most highly conventionalized forms. The median
design in figure 331 consists of a rectangle and two triangles so
arranged as to leave a rectangular white space between them. In figure
332 the median triangle is crossed by parallel and vertical zigzag
lines.
