Numerous examples, though mostly broken. The whorls 

 which are generally smootli are occasionally ornamented with 

 spiral striations, excepting the last one. Moreovei", just l^eneath 

 the sutures the whorls do not immediately slope but somewhat 

 bulge, so that the sutures become more oi- less channelled. The 

 figured specimen shows such a character.
