Catalogue entry no. 326 by Max Loehr:
326 Huang, Disk Segment with Notched Ends
Slightly larger version of the preceding type, No. 325, with the arc about 180 degrees. This huang is carved from a darker green jade, but the design of the birds differs from that in No. 325 only in small details. There are more ample remains of cinnabar, present on both sides. Middle Western Chou.
