Shell rather minute, very hke Bui. Maderensis, Lowe, in shajie 

 and colour, allied to Ach. folliculus, from which it differs, be- 

 sides the size, by being attenuated gradually from a broailer 

 base, by its ajjerture rather narrowed al)ove, by its labnim arcu- 

 ately prominent above, and by the columella being distinctly tnin- 

 cated and prominent. It (hffers from A. gracilis, Lowe, in being 

 more oblong, not fusiform, by its spire, which is extremely blunt, 

 and by the above-enumerated characters of the apeitme, labrum 

 and columella {Lowe).
