"It differs from this species [Ci/dojjhorus indicns'] in its more 

 elevated form, indistinct keel, rounded last whorl, moi-e elongate 

 aperture, porrect inner lip, the absence of any sinuosity in the 

 plane of the aperture on the columellar lip, less expanded outer 

 peristome, and by tlie greater expansion of the external columellar 

 lip over the umbilicus, which is also much narrower; and permits 

 no view of the internal whorls." (Benson.)
