The streaks generally extend to the suture above, though becom- 

 ing narrower or diluted, and may either continue to the base or give 

 way to a white patch around the columella. They are often more or 

 less zigzag, and on the base tend to become darker and confluent. 

 They are not interrupted by a light peripheral girdle. In one of the 

 specimens before me the upper whorls are banded as in young A* 

 sultanus, and the apex is purple. In the others it is white. One 

 of seven specimens before me is sinistral.
