The figure given by Pallas and copied by Martini is 

 apparently that of a larger shell than the specimen 

 figured in Sowcrby's Thesaurus; but in other respects 

 the characters acrree.

 midal ; whorls rounded, liardly touching ; varices 

 equidistant, laminated, extant, raised into an 

 acuminated angle ; aperttire subovate, outer lip

This species differs from Scalaria alata in being 



narrower, and in the shape of tlic varices and margin 

 of the aperture. In each species there is an angle on 

 the varix, but in Scalai-id fasciata it is much mon; 

 pointed and elevated than in Scalaria alata, and leans 

 towards the whorl. .
