 Obs. This is the finest specimen I have ever seen 

 of this extremely rare shell. Besides the longitudi- 

 nal white zigzag lines upon a fawn coloured ground, 

 there are four transverse bands, very little darker 

 than the ground colour itself. The dark chesnut 

 edging to the expanded columellar callus is a princi- 

 pal character of this shell.
