A single example from Kikondja (J. Bequaert Coll.) agrees well with 
Jickeli’s description and figures. He says nothing about internal teeth, 
but his figure 24c appears to show traces of one or two. In the Katanga 
specimen four long radial teeth may be seen through the base; beyond 
the distal end of each one a very short tooth is seen above the periphery. 
Diameter, 3.0 mm.; altitude, 1.25 mm.; 4 whorls.

Kisanga River, an affluent of the Kafubo, near Elisabethville 
(Michael Bequaert Coll.). 
This form is distinguished from S. angusta Jickeli by the relatively 
high form, the abrupt angulation of the periphery close to the left side, 
the latter being broadly concave, and the narrower aperture. A set. 
of three teeth, placed as in S. nitida, is seen at the last third of the last 
whorl. 
Diameter, 3.25 mm.; altitude, 1.4 mm.; 4% whorls.

synonymize this with S. angusta, but we cannot accept that view.
