(The late Mr. G. Yamagawa said about the identification of ^, niiyponensis 

 PiLS, that ahhough Pilsbry did not pointed out the distinct character 

 of this species, thero seeius no need to distinguish it from some 

 other Area species, especially A. satowl Dkr., and moreover it seems 

 certainly to be a young shell. In the shape of shall, thrre is indeed 

 some difference, but such variation is rather common among many 

 individuals, which has not any valu'3 to make a distinct species, and 

 so I have regarded A. nipponensu as a synonym of A. satowi Dkr.)
