Margaritana nchrasccnsis Meek. Dakota group of the Cretaceous series.Fig. 7. Left side view. The species, U. stcwardi resembles a common type of Unio in the Missis-sippi fauna. The figured specimen of U. macropisthus is the only one discovered. Itsposterior breadth probably indicates that it is a female. The species, U. iridoides, closely resembles U. iris, of the Mississippi fauna. Margaritana nebrasccnsis is much more inflated, especially in the umbonalregion than is any known living species of that genus; but it is known topossess the hinge structure of Margaritana.
