P. lechatelieri, Dautz.^, from Dahomey ; from this it is 

 distinguished by its more acute spire, submainillary apex, 

 broader base, blunter peripheral carina, coloured columella 

 and parietal callus, flatly furrowed sculpture, and general 

 colouring, which in P. lechatelieri is generally darker, espe- 

 cially on the base, while the chestnut bands on the spire are 

 more pronounced, numerous, and generally confined to the 

 lower portion of the whorls, which is not the case with 

 P. balesi,

Shell oblong-turrite, flesh-coloured, irregularly painted 

 with blotches and streaks of dark brownish purple and cream-

 the embryonic whorls very flat, constricted and quite smooth, 

 the later whorls gradually increasing, sculptured with fine, 

 slightly wavy, spiral striae and transverse growth-lines, the 

 last whorl carinate at the periphery ; sutures lightly im- 

 pressed, subcrenulate; columella greyish brown, descending 

 somewhat obliquely and extending into a thin, minutely 

 granular callus which reaches the lip above; peristome
