Larger, more elongate than typical P. africana; summit very obtuse 
(but very exceptionally individuals with an exserted spire occur, as 
shown in PI. XI, fig.8,8f). The penult whorl is either regularly rounded 
or somewhat flattened on both sides of a more strongly curved median 
zone. The outer lip at its insertion makes a much larger angle with the 
whorl than in africana, but this angle varies somewhat. The highly 
polished surface often shows traces of minute axial wrinkles cut by spiral 
impressions. The columella is generally rather abruptly truncate, but 
in other examples in the same lots, rather weakly and more obliquely 
terminated. Specimens from Lubumbashi measure: 
Length, 20.0 mm.; diameter, 13.5 mm.; aperture, 15.0 mm.; 4°4 whorls. .
