* Shell resemWing Cor JttZa, thin, smooth, or concentrically striated, inequi valve, inequilateral; anterior side short, rounded, posterior produced, obliquely truncate, gaping; left 

 valve with a ridge from the umbo to the postero-inferior end. Hinge unknown. Type, M. Croivcombeia, Moore, from Ehsetic beds at Beer-Croweombe. Except by its thin structure, 

 this shell does not appear to differ from Corbida. It is not stated which of the valves is the larger one, but the figure appears to indicate that the right valve is the larger one, which 

 is also usually the case in Corbula,
