 " Shell oblong, cylindrically conical, narrowly perforate, 



whitish or a pale rosy tint, varied with oblique brown stripes, 

 which at times become broader or blotchy at the lower part 

 of the whorls. The latter are 8 in number, rather convex 

 and slowly enlarging, obliquely striated by the lines of 

 growth, divided by a simple subhorizontal suture. Last volu- 

 tion oblong, a little attenuated at the lower part. Aperture 

 inversely subauriform, whitish or pale rose within, equalling 

 rather more than one-third of the entire length of the shell. 

 Peristome (viewed laterally) oblique, a little tortuous, thin 

 at the edge, and inconspicuously thickened within. Colu- 

 mella spirally contorted, bluish, and reflexed over the per- 

 foration at the upper part, brownish inferiorly, and grad- 

 ually curving into the basal margin of the aperture. Paries 

 coated with a thin callosity. Length 44 mm., diam. 17 ; aper- 

 ture 16 long, 8 wide " (Smith).
