With the form of &. Leppant, Stur., the arrangement of 
plaits in £. craterodon is quite different, the labial tooth being 
also more developed. A basal process is also present. 
EL. Arnoldi, Stur., is like in form of peristome, but the whorls 
in that species are far more tumid and it is also smaller in 
every detail.

Fab. Lower Umfolosi Drift, Zululand (Burnup). 
A species with remarkably elaborate mouth-processes, 
almost closing the roundish aperture, and suggesting the 
specific title proposed. These processes consist of :—(i.) a 
simple, oblong, internal, parietal plait; (ii.) a multiplex 
labial, thrice-divided and curving inwards; (ili.) a small, 
simple, basal tooth; and (iv.) a columellar plait, wholly 
internal, large, and subdivided centrally by a deepish furrow. 
The surface is white and polished, with the slightest sign of 
longitudinal striation at the extreme base only. It is a very 
distinct form.

The chief peculiarities of this very refined little Hnnea 
appear to consist in the bifid parietal and curious scimitar- 
like, incurved, and duplicated labial plait; the longitudinal
