Original description : — " Shell broadly umbilicate, depressedly 

 turbinate, and, in the single aged specimen found, decorticated, 

 whitish and smooth throughout. Traces of a brown epidermis 

 remain around the umbilicus, and younger specimens are probably 

 brown in colour, and perhaps ornamented with coloured bands, 

 like other species of the genus. Spire raised, depressedly conical, 

 suture deep, apex acute. Whorls 4| rounded ; the last cylindrical, 

 descending, and free near the aperture, and provided above, about 

 three millimetres behind the mouth, with a rather elongate tube, 

 which projects forward, and is in contact with the penultimate 

 whorl throughout. The tube appears broken at the end, and may 

 have been even longer originally ; the anterior termination in the 

 specimen is in a line with the oblique peristome of the shell. 

 Apertun^ diagonal, circular; peristome double, inner lip sharp, not 

 projecting much, curved backwards near the penultimate whorl ; 

 outer ])eristome expanded, and wavy above externally and below, 

 straight and somewhat narrower on the left margin. Operculum 

 nearly flat externally, concave within ; the outer margins of the 

 whorls free and lamellar, except towards the middle ; the circum- 

 ference surrounded by several raised lines, the edges of the outer- 

 most whorls. Major diameter 12| mm., minor 10^, axis 7, 

 diameter of the mouth 5^ mill." (Blanford.)

" This species differs from all others of the genus by its higher 

 spire, and by the combination of the mouth being free and the 

 sutural tube being directed forward and attached to the last 

 whorl." (Blanford.)
