Fossils from the Upj^er Mnsashino ^.i t\aziisa and Shiuiosa. 45 



flatly rounded, wider than interspaces, somewhat obh'que, nearly 

 straight, curving slightly toward the front at the upper end. Spiral 

 striae about twelve on the penultimate whorl, alternately large and 

 small. Body-whorl higher than spire with ribs gradually weaken- 

 ing on its base, while spiral striae are numerous and conspicuous 

 down to the caudal end. Aperture rliomboidal, pointed behind. 

 Inner lip with a thin callus. Outer lip thin. Sinus shallow, 

 rounded, close to suture. Canal short, wide, a little bent. 



In the single specimen obtained, the apex and the lips are 

 broken. The diameter is about 6 millim. The height, if the shell 

 is perfect, would l)e about 16 millim. 



This shell is closely related to Bela pyramidalis Stroem (Mart- 

 u. Chemn., Syst. Conch. Cab., IV, part 3, p. 159, pi. 32, fig. 14) 

 of Polar Seas in which, however, the ribs are sigmoidal.
