and arrangement, except that a small space close to suture is marked only 
by waved scratches, and there are 5 or 6 spirals on edge of shoulder sepa- 
rated only by linear interstices. Spire markedly scalar, about same height 
as aperture and canal. Keel on whorls is level with suture, so that shoulder 
is quite horizontal. Base and suture as in previous species. Aperture 
imperfect, outer lip being broken away, but from previous rest-marks it 
is clear that notch on shoulder-edge was practically absent. Columella 
lightly curved and bent to right, bearing 3 plaits and a few indistinct ridges 
outside these ; plaits progressively more sloping, the two upper ones strong, 
but the lowest very weak and almost vertical. Inner lip reflected as thin 
glaze over parietal wall, and as sharp free edge below fasciole, which forms 
a broad, rounded, and but slightly roughened ridge enclosing a chink-like 
but distinct umbilicus. Anterior notch evidently weak, much slighter and 
less reflected than in previous species. 
Height, 40 mm. ; diameter, 22-5 mm. ; height of aperture, 20 mm. 
Type and one much broken larger specimen, from Chatton, near Gore 
(Waiarekan ?), in author's collection. Named after the collector, Mr. E. M. 
Christie, M.Sc., of Gore High School. 
osely related to and congeneric with the previous species, but differing 
from it mainly in the horizontal shoulder, much weaker anterior and 
posterior notches, and much finer axial sculpture.

Shell small, biconic, pointed at both ends, more sharply posteriorly, 
with finely tuberculate spiral sculpture, Protoconch small and smooth, 
slightly oblique, twisted below, with 4 thin but strong oblique plaits, 
anterior pair much closer aud feebler ; canal short, open, and lightly notched, 
fasciole rather prominent. Inner lip drawn out to a fine point below.
