ture. In one of the specimens, there are three broad varices on^ 

 the whole shell, two on the body-whorl and one at the end of the 

 penultimate. Umbilicus open, narrow. The three spiral chestnut- 

 bands fovuid on the body-whorl of recent specimens can still be 

 seen also on the fossil. The largest example measures 11 millim. 

 in height and 5 millim. in diameter. 



Fossil occurrence. — Otake (rare) and Kioroshi (do). 



Living. — Central Japan.

A. Adams and Eeeve give the diagnosis of this species as 

 follows : 



' ' Shell longly turrete, hardly umbilicate. ^Miorls ten, round- 

 ed, smooth, polished. Ribs annular, subdistant, thin, broader and 

 flexuous near the suture. Colour bluish white with dark spots 

 (two between annular ribs). ' ' 



There are several specimens of this nice shell which measure 

 up to 20 millim. in height and 9 millim. in diameter. The ribs 

 number nine on the ultimate as well as on the penultimate whorl. 

 In one specimen the original dark dots are preserved as brown ones 

 placed one above the otlier. 



Fossil occurrence. — Otake (not rare). 



Living. — Western Japan (according to Iwakawa). China Sea.

Shell turriculate. Whorls many (about ten ?), very convex, 

 longitudinally costellate and spirally striate. Costellie about seven- 

 teen on the body-whorl, thin, lamellar, erect, aculeate at shoulders, 

 generally equal in size in young specimens, though in adult ones 

 some may grow larger and become varix-like. Spiral striae found 

 only between the costellce, many, equidistant, with one or more
