Long. 16; lat. 12; diam. 7 mill. Hob.—Africa. Collect. Prime. The shell is transversely oval, somewhat compressed, and very inequilateral. The lateral margins are rounded. The beaks are small, raised, acute, they curve inwardly, they are approximate and very much inclined. The valves are slight. The interior is pale violet. The striae are regular. The epidermis is pale greenish with violet markings on the beaks, and is polished. The hinge is quite narrow and nearly straight. The posterior lateral tooth is longer than the posterior tooth. The lunula is oval and yellow. The very inequilateral appearance of this species renders it quite distinct. 29. Corbicula solidula, Prime. Corbicula solidula, Prime. Acad. K S. Phil. Proc. 12*7.
