This West African form is about intermediate between 

 coenopictus and lardeus in proportions, the spire almost 

 straightly conic, the peristome broader and flatter than in 

 typical coenopictus, of which it should probably be considered 

 a local race or subspecies, if indeed it is at all separable. A 

 Goree specimen measures: length 5.2, diam. 2.5, length of 

 aperture 2.1 mm. ; 6 whorls.
