half, marked by many microscopic, subspirally arranged, elongate-oval 

 papillae. Post-nuclear whorls four and one-half, well rounded, some-

 the summit falling halfway between the dark spiral band and the base 

 of the columella; slightly constricted behind the fairly well devel- 

 oped and somewhat reflected peristome. Columella obliquely curved, 

 much expanded and decidedly reflected at the base where it almost con- 

 ceals the umbilicus. Aperture large, oblique, rounded.
