black, and the spire of a darker tint, becoming purplish 
towards the apex, with a black infrasutural line and traces of 
a whitish periostracum forming oblique streaks in the direc- 
tion of the lines of growth, more or less interrupted by fine 
spiral lines. This epidermal ornamentation is referred to by 
Kobelt. 
Other specimens (var. concolor, nov.) are of a uniform 
whitish colour beneath the pale greenish-yellow or ochraceous 
periostracum, and the peristome is margined with pinkish 
purple-brown or purple-black. All specimens appear to have 
a white tooth-like prominence or thickening on the columella.
