raised strive; whorls 73, barely convex, slowly increasing, first four 
tapering from a rather obtuse apex, back of last whorl constricted by 
two folds; aperture with a prominent, somewhat short, parietal plait, 
a little distance from the right margin of the peristome, two parallel 
basal lamine far within, the left-hand one only just visible from the 
exterior, at a half-whorl from the peristome there is another parietal 
(spiral) plait, and the aoa is pressed out into a broad tooth-hke, 
projection extending half-way across the opening ; peristome slightly 
expanded, margins joined ne a thin callus. Diam. maj. 6:5, alt.

Ennea affectata, n.sp. 
Hab.—Zanzibar. 
This species is quite distinct from any other of the genus known 
to me. nnea trigonostoma, Marts., 1s somewhat similar in its 
general characters, but is larger, not so cylindrical, and its basal plaits 
are placed quite forward, not far back within the interior as in 
LE. affectata,
