solid; white under a pale olive-tawny cuticle, streaked here 

 and there with darker, and but little deciduous, glossy. Spire 

 moderately tapering, broadly truncate; suture impressed. 

 Whorls remaining 7, slightly convex, rather narrow; orna- 

 mented with slightly arcuate, subobliquely longitudinal rib- 

 lets, which are somewhat irregular, peculiarly wrinkle-malle- 

 ate, and the color of the rest of the surface. Last whorl a 

 little descending, shortly free, slightly produced forward, a 

 trifle subangular above, with a slight inconspicuous, thread- 

 like carina below the middle. Aperture a little oblique, sub- 

 angulate-rounded, white inside; peristome continuous, thick- 

 ened, narrowly reflexed throughout, white, the columellar 

 margin hardly plicate within. Length 44, diam. 14 mm.; 

 aperture with peristome 10% mm. long, 10 wide (C. & F.)

* ' Agrees in its malleated sculpture, as well as in color, with 

 E. blandianum," but is much smaller, with shorter whorls and 

 rounded aperture. According to Strebel the internal pillar 

 is exactly like that of E. blandianum.
