Species of Shells from Japan. 



371 



This fine species is a typical Buccinum, but does not exhibit 

 any of the longitudinal plicae characteristic of B. undatum. 

 The whorls are peculiarly rounded and swollen, while some- 

 what depressed at the suture. The whole surface of the shell 

 is closely and regularly sculptured with fine waved grooves.
