Smaller, narrower, and more cylindrical than E. drakens- 

 hergensis, M. & P., and in general form more resemblinj^ 

 E. cari/oti'sj M. & P., but differing from that species entirely 

 as regards the disposition of the oral plaits and teeth. It 

 ma}' be compared also with E. viontana, M. & P., from 

 ^fountain Drive, Grahamstown, the aperture of which is 

 trigonous, with finer and closer spirals on the whorls.

Alt. 6, diam. 3 mm. 



Hah. Melmoth, Zululand, at 8000 feet, with " no water 

 near the spot^' {Miss Ilicby). 



Several examples of a pellucid, very smootli and shining 

 Ennea, eight-whorled, oval or oval-oblong in form, with very 

 complicated ])eristomatal processes, the most peculiar being 

 the tlirice or four times divided labial tooth or plait, proceeding 

 deeply within, and irregularly serrulate. The moderately- 

 sized basal tooth is squarely oblong, the columellar process 

 wliolly internal, half closing the orifice below. 



We take as the type the ovate form. One specimen is 

 decidedly oblong, in all other respects similar.
