long, attenuated in front. Suture oblique, slightly impressed, 
irregular. Mouth long, but not wide, oblique, with its two sides 
nearly parallel, bluntly pointed above, ending below in a broad, 
shallow, slightly emarginated, minutely bordered canal. Outer 
lip patulous, thin, but expanded and rounded on the edge; it 
rises on the penultimate whorl at its junction, and is here drawn 
back into a slight sinus with a very reverted edge. Inner lip 
spreads widely as a thin glaze on the body ; above it is scarcely 
convex, hardly concave in the middle, perpendicular below, 
where are four, not strong, equal, concealed, pale-coloured, very 
oblique teeth ; obliquely cut off, twisted and rounded in front 
into a prominent thin point. H. 2.75; B. 1.25. Penultimate 
whorl, height, 0.53. Mouth, height, 1.73 ; breadth, 0.6. 
This species is suggestive of many others, and may be com- 
pared with Voluta rupestvis, Gm., V. pacifica, Sol., V. lyriformis, 
Vigors, and V. fulminata, Lam., but resembles most V. megaspiva, 
Sow., having the same long thickened lip and form of body- 
whorl, but in that species the spire is higher and is fine.

N. E. from New Zealand. 7o0o fms., grey ooze. Bottom tem- 
perature 40°. 
Shell—Rather small, thin, chalkily porcellaneous, ovate, with. 
a shortish scalar spire, a rounded apex, a marginated suture, 
whorls rounded and beset with small prickles, a tumid base and 
a very short pillar. Sculptuve—Longitudinals—There are on 
each whorl about 20 narrow feeble ribs, which do not extend to 
the upper whorl and die out on the base; the lines of growth 
are fine, flexuous, and close-set. Spirals——There are on the 
penultimate whorl four broadish but very slightly raised threads ; 
in crossing the longitudinal riblets these rise into small prickles, 
or pointed tubercles; on the body-whorl there are 5 or 6o0f © 
these, and 4 or 5 more on the base, which latter are sharper, 
higher, and less tuberculed ; below the suture there is a short 
base, more or less flat shoulder ; round the base of the pillar is 
a small sharp spiral, which is continuous with the upper edge of 
the canal ; the back of the pillar is scored with very undulating 
lines, the scars of the old canal. Colour chalky white. Spire 
rather short, more or less scalar, with a convex outline. Apex 
blunt and rounded, consisting of nearly 4 largish, smooth, tur- 
binate, convex whorls, of which the highest is immersed. Whovrls 
7, stumpy, convexly cylindrical, flatly shouldered above; the 
last is tumid, with a very rounded, almost inflated, and short 
base, on which, looked at from behind, the point of the pillar is 
barely discernible, and the edge of the canal does not project at 
all. Suture impressed, flatly marginated below, very horizontal. 
Mouth a perfect oval all round, having no angulation above, and 
though cut on the edge, yet being in its sweep quite uninterrup- 
ted by the canal in front. Outey-lip thin, sharp and patulous,
