Catalogue entry no. 138 by Max Loehr:
138 Small Fish-shaped Chisel
Opaque, gray-green and blackish, much calcified jade object, shaped as a straight fish figure in the round with a short wedge-like extension beyond the tail. The head, with its protruding eyes and obtuse nose, and the row of incised rhombi in place of the dorsal fin, are feature that distinguishes this fish from the more usual types listed above. The pectoral fins and two low ridges marking the tail fin, on the other hand, are commonplace omelets. Shang.
