The lunula is pallid. The sulci are regular. The epidermis is po- lished and of a pale greenish color. The hinge is strong. Compared with Corb. Primeana, it is smaller, more equila- teral, fuller, the beaks are more inflated, the sides are less angu- lar, and the coloring is darker. I take much pleasure in dedicating this species to Mr. Isaac Lea, who was kind enough to lend it to me for description. 13. Corbicula Japonica, nov. spec.
