This West African form is about intermediate between 

 cocnopictus and lardeus in proportions, the spire almost 

 straightly conic, the peristome broader and flatter than in 

 typical cccnopictus, of w T hich 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 

 iiperture 2.1 mm.; 6 whorls.
