The body of the conventionalized bird is decorated with terraced figures, spirals, flowers, and other designs arranged in a highly complicated manner. From a bar connecting the spiral with the encircling line there arises a tuft of feathers. Figure _a_ of the same plate is characterized by a medially placed triangle and a graceful pendant from which hangs seven feathers. In this instance these structures take the form of triangles and pairs of lines. The relation of these structures to feathers would appear highly speculative, but they have been so interpreted for the following reason: If we compare them with the appendages represented in the design on the vase shown in CXLIII, _b_, we find them the same in number, form, and arrangement; the triangles in the design on this vase are directly comparable with the figures in plate CXLIII, _b_, in the same position, which are undoubtedly feathers, as has been shown in the discussion of this figure. Consequently, although the triangles on the pendant in plate CLIII, _a_, appear at first glance to have no relation to the prescribed feather symbol, morphology shows their true interpretation. The reduction of the wing feather to a simple triangular figure is likewise shown in several other pictures on food vessels, notably in the figure, undoubtedly of a bird, represented in plate CXLVI, _a_. In the two figures forming plate CLIV are found simple bird symbols and feather designs very much conventionalized. The same is true of the two figures given in plate CLV. The vessels illustrated in plate CLVI, _a_, _b_, are decorated with designs of unknown meaning, save that the latter recalls the modification of the feather into long triangular forms. On the outer surface this bowl has a row of tadpoles encircling it in a sinistral direction, or with the center of the bowl on the left. The design of figure _c_ shows a bird's head in profile, with a crest of feathers and with the two eyes on one side of the head and a necklace. The triangular figure bears the symbolism of the turkey feather, as at present designated in Tusayan altar paraphernalia. As with other bird figures, there is a representation in red of the triple star. Figure _d_ is the only specimen of a vessel in the conventional form of a bird which was found at Sikyatki; it evidently formerly had a handle. The vessel itself is globular, and the form of the bird is intensified by the designs on its surface. The bird's head is turned to the observer, and the row of triangles represent wing feathers. The signification of the designs on _e_ and _f_ is unknown to me. Figures _e_ and _f_ of plate CLVI are avian decorations, reduced in the case of the former to geometric forms. The triangular figure is a marked feature in the latter design.
