Japan, 



(Group of Nodularia sagittaria.) 



Shell elongated, the hinder point above the middle of the shell, with 

 a sharp posterior ridge and a faint ridge above it; beaks rather low, 



'Kobelt figured this for Lea's species, and it seems to me to be an old, solid, slightly 

 arcnate form, possibly worthy of a varietal name. 



-It is quite probable that this and the preceding species are only varieties of 

 X. japaitensis. 



3 The beaks of the specimen figured are greatly eroded. I can not be certain as to 

 the relationship of this curious form, but it probably is a Nodularia.
