ing scales, and below this folded in two spiral lines. In the 
body-whorl are four of these spiral foldings, progressively 
decreasing in size towards the base of the shell, in front of 
which the lamelle are crenulate as they run along the snout, 
which they cross to the right further and further forward as 
they approach the aperture. 
Dim.—Length, 13°9 mm.; of body-whorl, 98 mm. ;

Locality.—Type in 150 fathoms off Beachport: in 200 
fathoms, 2 good. 
73 recarvatus, n. sp. Pl. xxiv., figs. 7 and 573 
Shell fairly solid, elongate-conical, of 7 whorls, includ- 
ing a prominent conical protoconch of 24 smooth, convex 
turns, separated by a deep suture, and with a curious acute 
exsert apex. Spire-whorls short, wide; with very oblique 
simple sutures; swollen, sharply angulate just above the 
middle, below which in the body-whorl the base is rapidly 
contracted. Aperture roundly oval; canal about as long as 
the aperture, slightly deviated to the left, forming an open 
angle with the columella, markedly recurved. Outer lip 
thickened, equidistantly biangulate; inner lip inconspicuous. 
The sculpture consists of axial lamelle, thirteen in the penul- 
timate, which are folded into prominent scales at the angle; 
and in the body-whorl, at a spiral cord (which starts at the 
suture from the back of the aperture, runs round the base, 
and angulates the outer lip); and then crenated run over 
three obsolete spirals winding round the base, and finally 
bend in turn to the right over the back of the canal. It is 
of a uniform light-horn colour. 
Dim.—Length, 67 mm.; of the body-whorl, 3°6 mm.; 
width, 3 mm. 
Locality.—Type in 200 fathoms off Beachport. 
The recurved short canal distinguishes it from 7. plici- 
Zaminatus. 
cdadtbiaMitra arnoldi, n. sp. Pl. xxiv., fig. 6. £ 7, 
Shell solid, elongate-oval, of 7 whorls, including a blunt 
brown protoconch of 2 convex smooth whorls. Spire-whorls 
convex in the upper half, nearly straight in the lower. Suture 
distinct, very narrowly tabulate. Base moderately roundly 
contracted. Aperture elongate-oval. Outer lip simple, thin, 
profile slightly sinuous, with numerous spiral plice in the 
throat. Columella nearly straight, slightly cut away to the 
left in front, with four stout oblique plaits; notch with a 
narrow reflected edge. Wide, round, low axial ribs, much
