There is considerable variation in degree of elongation, some shells 

 being high, subscalariform. These have received the varietal name 

 of sohdus Fischer (pi. 38, fig. 17). The number of lirte on the 

 penultimate whorl, their equality in size, and the coloration, are the 

 more salient specific characters. *
