The most instructive of all the appendages to the body are the club-shape bodies, one on each side, rising from the point of union of the wings and the breast. These are spatulate in form, with a terraced terminal marking. They, like other appendages, represent feathers, but that peculiar kind which is found under the wing is called the breath feather.[144] This feather is still used in certain ceremonials, and is tied to certain prayer offerings. Its ancient symbolism is very clearly indicated in this picture, and is markedly different from that of either the wing or tail feathers, which have a totally different ceremonial use at the present time. For convenience of comparison, a number of pictures which undoubtedly refer to different birds in ancient interpretations will be grouped in a single series. Plate CXXXVIII, _d_, represents a figure of a bird showing great relative modification of organs when compared with those previously discussed. The head is very much broadened, but the semicircular markings, which occur also on the heads of previously described bird figures, are well drawn. The wings are mere curved appendages, destitute of feather symbols, but are provided with lateral spurs and have knobs at their bases. The body is rectangular; the tail-feathers are numerous, with well-marked symbolism. Perhaps the most striking appendages to the body are the two well-defined extensions of parts of the body itself, which, although represented in other pictures of birds, nowhere reach such relatively large size.

CXXXIX FOOD BOWLS WITH FIGURES OF BIRDS FROM SIKYATKI] The figure of a bird shown in plate CXXXVIII, _c_, is similar in many respects to that last described. The semicircular markings on the head of the former are here replaced by triangles, but both are symbolic of rain-clouds. The wings are curved projections, without any suggestion of feathers or basal spurs and knobs. The tail-feathers show nothing exceptional, and the body is bounded posteriorly by triangular extensions, as in figures of birds already described. The representation of the bird in plate CXXXVIII, _e_, has a triangular body continued into two points on the posterior end, between which the tail-feathers are situated. The body is covered with terraced and triangular designs, and the head is rectangular in form. On each side of the bird figure there is a symbol of a flower, possibly the sunflower or an aster.
