460 Mr. A. Adams on the Species of 



Pfr., at Port Hamilton; but these localities belong to the 

 Korean archipelago, which I have not included in my enu- 

 meration of Japanese Mollusca. Helix [Plectotropis) elegan- 

 tissima, Pfr., is stated to have come from Japan ; but I never 

 met with that charming shell during my explorations. 



In a future communication I shall examine the remainder 

 of my Japanese Helicidse, comprising the subfamily Pu^inw.
