Shell large, depressed, umbilicated, fairly solid, irregularly plaited, 

 shining, fulvous with brown spiral bands. Sculpture : Upper surface 

 irregularly radially plicated, the plaits following the direction of the 

 fine retractive and flexuous growth-lines, which are crossed by fine 

 and dense spiral striae, stronger, somewhat irregularly wavy and more 

 or less interrupted on the last two whorls ; the base smooth, polished. 

 Colour fulvous or yellowish-olive, ornamented with thickly set un- 

 dulating chestnut-coloured spiral lines, which show very great vari- 

 ability in width, disposition, and depth of colour ; the umbilical 

 tract is either yellowish or brown ; aperture bluish-grey or bluish- 

 black, the parietal callus grey or whitish, sometimes light brown. 

 Epidermis rather thick, viscidly shining on the upper surface, polished 

 on the base, extending beyond the peristome. Spire scarcely elevated, 

 with the crown thin, obtuse. Protoconch of 2 whorls, broadly convex, 

 very often eroded. Whorls 5 to 6. first rather slowly increasing, 

 slightly convex, the last depressedly rotundate, often descending in 

 front, rounded or subangulated at the periphery, irregularly hollowed 

 beneath. Suture impressed. Aperture very oblique, lunar. Peri- 

 stome somewhat inflexed, straight, advancing above. Columella very 

 oblique, arcuate, slightly expanded above ; parietal wall with a con- 

 spicuous callus. Umbilicus moderate, oblique, not pervious.
