 more conspicuous numbering about 15 on the body- whorl, 

 5 or 6 on the next whorl, and decreasing upwards ; the third 

 whorl has several minute curved striae in the line of growth, 

 their interstices being pitted, or the striae granulated, by the 

 intersection of four or five equally minute spiral striae ; the 

 top whorls are smooth and glossy : colour yellowish- white, 

 orange, or occasionally deep reddish-brown ; paler specimens 

 sometimes exhibit traces of a broad orange band below the
