one end. 
In the present list I have restricted the genus Chemnitzia to those 
species which are longitudinally ribbed, and in which there is no tooth 
on the columella: when there are teeth, they belong to Pyramidella 
properly so called. The smooth species with teeth are Obelisci, and 
those without teeth Hulimelle: the Odostomie are ovate, with a 
single tooth.
