Obs. — This species is run into Alaba semistriata, Philippi, by 

 Tryon, but we are not satisfied that this is correct. The shell 

 we have as representing the above species appears closely related 

 to D. lauta, A. Adams, but is usually a thin translucent dark 

 coloured and smaller form, and may, as a rule, be picked out 

 from small examples of D. lauta. In the original description it 

 is recorded as not uncommon in the Korea and Japan.
