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. Helia (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 Helicide, comprising the subfamily Pupine.
