262 Bird Figure
Slightly calcified, translucent yellowish brown jade. The bird has a short tail and a rather compact shape, but its hammer-shaped beak and crest relate it to the preceding types. The eyes are comparatively large, and the interior, grooved design, identical on both sides, is reduced to a few lines marking wings and tail. Small perforation at the breast. Late Western Chou.
