 hardly seen with the ordinary hand lens. Vertex narrowly im- 

 pressed, imperforate, the slightly thickened outer lip arising from 

 the right side of the center, produced high above the vertex ; outer 

 lip produced forward above. Aperture more than twice as wide 

 below as above ; columella very concave ; parietal callus light. Alt.

 believe, absolutely synonymous.
