The upper valve, in the specimens from the Gulf of Siam, has a peculiar 

 wrinkled (in the younger specimens nodose) appearance; the interior has a nacreous 

 lustre. A. plenilunium, Reeve (from Borneo, Mergui Isis, and several other places) is, 

 no doubt, only A. sol. Reeve, although Reeve states that "The under valve is tumidly 

 raised about the orifice, with flexuous lines diverging around;" this is undoubtedly 

 only an individual character.
