Testa mediocriter umbiliccda, depresso-turbinata, solidiuscula, epi- 

 dermide crassd, fused, liris spiralibus sub-confertis et lineis elevatis 

 confertissimis obliquis decussation ornatd ; intra suturam, ad peri- 

 plieriam, atque circa umbilicum pilis longiusculis confertim fimbriates 

 induta ; sub epidermide edbida, decussato-costulata, liris spiralibus

Shell umbilicated, depressly turbinate, rather solid, covered with 

 a thick dark coloured epidermis, which has strong raised decussated 

 sculpture of spiral ridges and very close oblique costulation : at the 

 periphery and around the umbilicus there is a fringe of close, rather 

 long hairs, and the outer series continued on the inner whorls forms 

 a sutural fringe also. Beneath the epidermis the shell is white with 

 decussating lines, the spiral sculpture being more pronounced and the 

 ribbing corresponding to the lines of growth less so than outside the 

 epidermis. Spire convexly conoid, the apex prominent and papillar, 

 suture deep, nearly concealed by the hairy fringe within. Whorls 

 5 — 5J, convex, the last cylindrical, descending but very little in 

 front. Umbilicus pervious, exhibiting all the whorls, spirally ribbed, 

 partly covered by the surrounding hairy fringe. Aperture diagonal, 

 round, rather milky inside, with dark horizontal lines corresponding 

 to the spiral ribs on the shell ; the peristome is thick and double, 

 curved backwards near the umbilicus, the internal portion with 

 minute pearly white denticulations, largest on the outer (dextral) 

 margin and gradually decreasing slightly in size on the upper and basal 

 edges, vanishing entirely near the umbilicus ; the external peristome
