narrow darker growth-striae showing here and there. The 

 sculpture consists of line, pretty closely crowded riblets, dis- 

 tinctly raised from the somewhat horn-colored background, 

 and about 135 in number on the penultimate whorl, which is 

 12 mm. in diam. In the interstices there is fine, rather regu- 

 lar spiral plication, which is not everywhere distinct. The 

 iy 2 to Sy 2 whorls remaining are narrowly and weakly mar- 

 gined. The last whorl is shortly free and produced at the 

 aperture, at first more or less distinctly keeled, later having 

 a more or less distinct cord. The peristome is shortly ex- 

 panded, almost reflexed and thickened with whitish inside. 

 The pretty strong, bar-like defined columellar fold is white and 

 the interior is lined with a thin, white layer of enamel.
