The back of the shell is bulging in the middle, and the two sides are thick and flat. At the back of the shell, which is equivalent to 1/3 of the shell length, the two sides suddenly expand to form a tumor-like protrusion. The shell surface is covered with glossy enamel, which is light yellow, bright yellow or slightly gray-green. The edges on both sides are lighter in color. There are 2-3 gray-green horizontal bands and not-so-obvious orange-yellow fine ring patterns on the back. The whorls are completely covered by enamel and have no ribs. Shell base flat, yellowish white. Shell base flat, yellowish white. The shell opening is long and narrow, and the surrounding area is white.

[Identification] For physical and chemical identification, place 100g of shells (passed through a 40-mesh sieve) in a test tube, add 15ml of distilled water, and observe its sedimentation coefficient and the amount of suspended matter. The sedimentation time of the annular clams is 2-12 minutes, with very little suspended matter; the sedimentation time of the clams is 15 minutes, with very little suspended matter; the sedimentation time of the clams is 15 minutes, with very little suspended matter.
