The diameter is about three-eighths, or sometimes half an inch, 

 and the length is rather more than half the diameter ; it has 

 six whirls, which are closely striated transversely, and the 

 striae, by crossing the sub-carinated margin of the body- 

 whirl, give it a crenulaled appearance when examined with 

 a glass, as Muller describes ; it varies much in its markings, 

 some shells being fasciated with brown and white, others 

 dark brown with a single white belt, and minutely spotted 

 with white, and some have brown bands running into each 

 other, and are elegantly spotted with white ; there are gene- 

 rally several small interrupted bands on the base, and the 

 umbilicus is rather large.
