but differs in being coarser, in wanting the strong and prominent
longitudinal furrows which characterise that species, and which
are observable throughout its length ; the outer lip also has a
tendency to be more produced ; while the flame-shaped streaks of
colouring are narrower, closer, and less devious or zigzag, often
becoming bifid or pronged on the body-whorl; epidermis pale
olive-green or olive-brown, ornamented with close, narrow, irregular
transverse dashes. General number of whorls in eroded and
decollated specimens five, though nine or ten would appear to
be the correct number, wrinkled transversely by coarse lines of
increase ; the upper angle of the aperture is never so acute as in
M. pyramis, and the sutures are deeper and whorls more tumid at
their junction.

" A remarkable form ; spire short, with ventricose whorls, substance
thick, coloration uniform green (or almost so), longitudinal
ribbing remarkably developed, even on the last whorl."

" A very distinct form remarkable for its ' terebra-like' produced
spire, its contracted or appressed whorls (especially the
last) ; the spiral, undulating sculpture is more acutely prominent
than in any form I know; all the whorls, except the last, have
a light longitudinal ribbing as well; of a light yellowish-green
colour, prettily marbled with brown. Anfr. 8 ; long. 27^, diam.
7-p^ mm."
" PI. 74, fig. 1 of the Con. Indica resembles it, only
the last whorl is too ventricose, etc."

" A form nearer Eeeve's fig. 109 B ; distinguished from the
preceding by the more developed longitudinal structure throughout."
