The shell is small, transversely-oval, trigonal, equilateral, 

 and somewhat compressed. The lateral margins are obtuse. 

 The striae are very regular. The epidermis is green and 

 polished. The lunula is indistinct and pale. The beaks are 

 very small and acute, they curve inwardly, are flesh-colored 

 and marked with a ray of dark violet. The interior of the 

 valves is violet. 



The Corbicula subradiata is very closely allied to Corbicula 

 radiata of Africa ; it is, however, more trigonal, less globose, and 

 the beaks are less tumid and less acute.
