Stuttgardt; Mns. Stockholm et Prime. The shell is orbicular, trigonal, compressed, and nearly equi- lateral. The anterior side is broader and more obtuse. The striae are close and regular. The epidermis is of a light green- ish olive color and polished. The interior of the valves is pur- plish-violet. The beaks are small, acute, and somewhat raised. The lunula is a little lighter in color than the rest of the shell. The original describer of this species, Dr. Krauss, is in error in referring it to the Corb. radiata and pusilla, as may be seen by a comparison of the Corb. Africana with these species. The Corb. pusilla is more globose, more trigonal, it is smaller, the coloring is different, the beaks are much fuller, and the hinge is much broader and more curved. The Corb. radiata is small- er, more globose, less trigonal, the coloring is not the same and the hinge is more rounded. 44. Corbicula ducalis, Prime. Cyrena ftuminea, Mousson. Moll.
