whorls, the apical simple, smooth, the rest obliquely thickly 

 costate, with transverse acute lirae, the interstices extremely 

 minutely decussate, the mouth is oblong, the sinus small, only 

 half-hollowed out of the outer lip, and not extending across, 

 the lip is much thickened, fimbriolate, within seven or eight

 times again anglicized).
