The dark stripes on each whorl divide into three parts : in 

 the middle broad, with wide light interspaces; above and be- 

 low by repeated splitting they are more numerous and finer. 

 The lower division is concealed on the whorls of the spire. 

 The eggs are 18 mm. long and 14 wide. [Probably an error 

 for 1.8 and 1.4.]
