Ildb.—In flumine Fuh Chan," Chinae. Col- lect. Wheatley et Prime. The shell is rounded-oval, equilateral, not much inflated, somewhat solid, the margins are generally rounded, the posterior margin is slightly obtuse. The hinge is broad and ro- bust, and the teeth are strong; the anterior lateral tooth is a little bent in the vicinity of the muscle. The interior of the valves is pale violet. The beaks are moderately inflated but obtuse, and they are often eroded. The lunula is indistinct. The sulci are distant, in young specimens they are very distinct, regular, much raised, and sharp, in the adult shell they seem at times to become nearly obsolete. The epidermis is polished and varies in color from light green to a dark ferru- ginous brown, the portion of the shell in the immediate vicinity of the beaks is most generally brown or black. I am at a loss to understand how this species, which is found quite commonly, should have escaped the notice of concholo- gists ; it has probably been confounded with Corbicula flumi- nea. Compared with that species it is very much smaller, much more transverse, less triangular, less ponderous, and less solid; Corbicula Miillerianru.
