The ground-color is extremely variable, every shade between 

 light buff or light olive-green and deep maroon being represented. 

 It is nearly uniform in tint, becoming pink on the earlier whorls in 

 most specimens. In about one-third of the specimens before me 

 there is a narrow dark band bordering the columella, generally not 

 very distinct. In any of the color-forms, from light to dark, bands 

 of close spots of hydrophanous cuticle are frequently developed. 

 The supraperipheral hydrophanous band is the most constant and 

 prominent.

Imperforate, globose, somewhat depressed, the spire generally 

 rather conoidal ; solid; ground-color (beneath the hydrophanous 

 cuticle) dark reddish-chestnut, sometimes yellowish-chestnut, usu- 

 ally with a light peripheral girdle. Covered with a cream-colored 

 or li!_rht brown cuticle, with a white zone at periphery. 



The hydrophanous cuticle is often closely streaked obliquely, and 

 nerally has some or many .spiral dark lines. The apical whorls 

 arc pink or purple-pink. Whorls 43-5, convex. Aperture wide- 

 lunar, pink or white inside; peristome broadly reflexed, typically 

 Imirht pink, but often white, with or without a pink edge. Colu- 

 mella pink or white, broad, irregularly arcuate.
