Catalogue entry no. 255 by Max Loehr:
255 Crested Bird
Translucent light gray jade with minute black speckles. The silhouette of the bird, whose raised head is distinguished by a curved, pointed crest, conforms to a triangle. A simple groove marks off the wings from the claws, belly, and tail. There are circular depressions around the eyes, and a perforation at the breast.
Western Chou.
