Fossils from the Upper Musashiiio of Kazusa and Shimosa. 93' 



shorter than the specimen figured by Dall and Bartsch (lue. cit. ph 

 XVIII, fig- 2). The number of post-nuclear whorls is al)out seven 

 and not ten as the authors say. 



The largest example measures 13 millim. in height with the 

 diameter varying from 4.3 millim. to 4.9 millim. (Dall gives: 

 Length 13.7 milhm. Diameter 4.4 millim.).

A single specimen. A long slender apically blunt shell with 

 about eight post-nuclear whorls which are peilectly fiat and ap- 

 parently smooth. Periphery and base rounded. Aperture ovate, 

 pointed behind. Columella-fold indistinct. Height 4.8 millim. 

 Diameter L3 miUim. 



The specimen agrees quite well with the figure and the de- 

 scription of the above species, save in the absence of minute spiral 

 striations which are said to be found in the living one examined by 

 Dall and Bartsch.
