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 Isls. and several other places) is, 
no doubt, only A. sol, Reeve, although REEyE states that “The under valve is tumidly 
raised about the orifice, with flexuous lines diverging around,” this is undoubtedly 
only an individual character.
