descending a little in front. Peristome thin, simple, receding sharply 
in profile from above. Columella very weak, concave, without marginal 
reflexion.

Type in British Museum. 
Hab. Carr Prntnsuta (generally distributed). 
This little species has been known for fifty years, but has been 
generally misidentified as vernicosa, Krauss, or bullacea, Pfr., under 
one of which names it appears in many museum and private collec- 
tions. It is a far smaller form than vernicosa, with the type of 
which I have compared it, while bullacea is an Australian species, 
non-existent in South Africa. N. vernicosa, var. minor, Pfr., from 
Natal, which I have not seen, may be near akin to tarachodes, but, 
if so, is worthy of specific rank.
