It is to some extent comparable with EL. differens, Sturany. 
A few examples.

E, testa rimata, breviter cylindriformi, nitida, fere levi, delicata, 
subpellucida; anfractibus 7, apicalibus obtusissimis, ceteris in- 
flatis, supernis angustis, penultimo latiore, apud suturas sub lente 
utrinque oblique striatis, striis in medio evanidis, ultimo anfractu 
levissimo ; apertura anguste trigonali; peristomate albo, nitido, 
dentibus plicisve sex instructo: plica parietali lata, haud intrante, 
truncatula, dente labiali bifurcato, parte superiore minore, dente

A shining nearly transparent little Hnnea, shortly cylin- 
drical in form, and smooth, excepting just round the sutures 
of the upper whorls, where, with a lens, slight oblique 
striation is discernible, the body-whorl being quite smooth. 
The peristomatal processes are six in number—a truncate 
parietal plait, two labial bifurcate teeth on a common base, a 
small basal tooth, acolumellar one much thickened, and below 
this last a mamillate plait. 
Ennea montana, sp.n. (Pl. XXXT. fig. 15.) 
#. testa cylindrica, doluformi, parva, subperforata, vitrea, vel in- 
erassata ; anfractibus 7, apicalibus obtusissimis, omnibus apud 
suturas multum impressis, in medio ad suturas utrinque oblique 
rudistriatis, striis apud medium anfractum evanidis; apertura 
trigona ; peristomate centrali, albo, incrassato, dentibus plicisve 
quatuor munito: plica parietali conspicua, dente labiali bifido, 
parvo, subtus acuto, dente basali minore, plica columellari interna. 
Long. 3°50, lat. 1°20 mm. 
Hab. Mountain Drive, Grahamstown (J. Farquhar).
