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. [Illustration: FIG. 329--Double triangle; median triangle] [Illustration: FIG. 330--Double compound triangle] 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. [Illustration: FIG. 332--Double rectangle; median triangle] [Illustration: FIG. 333--Double triangle with crooks] 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. [Illustration: FIG. 334--W-shape figure; single line with feathers] In the design represented in figure 333 there are two triangular figures, one on each side of a median line, in relation to which they are symmetrical. Each triangle has a simple key pattern in the middle, and the line from which they appear to hang is blocked off with alternating black and white rectangles. At either extremity of this line there is a circular dot from which extend four parallel lines. [Illustration: FIG. 335--Compound rectangle, triangles, and feathers] A somewhat simpler form of the same design is found in figure 334, showing a straight line above terminating with dots, from which extend parallel lines, and two triangular figures below, symmetrically placed in reference to an hypothetical upright line between them.
