STJTEE : ON MOLLUSCA FEOM NEW ZEALAND. 185 



microscopically spirally striate, the nucleus oblique, rounded, the 

 second volution with a sharp median keel. Whorls 7, regularly 

 increasing, roundly angled at the middle by the nodules, concave above 

 and below it ; body- whorl slightly convex, contracted at the base. 

 Suture linear, bimarginate. Aperture oblique, oval, angled above, 

 produced below into an oblique, short, and open canal, slightly notched 

 at its base. Outer lip sharp, somewhat strengthened outside, 

 moderately convex, contracted below, with a fairlj'- deep and rounded 

 sinus in the depression above the row of nodules. Columella slightly 

 arcuate, excavated on meeting the parietal wall ; inner lip thin and 

 narrow, drawn out to a point towards the margin of the canal. 

 Operculum unknown. Diameter 3-9, height 9 mm. 



Sab. — Dredged off Otago Heads (A. Hamilton). 



Allied to D. Wanganuiensis, Hutt., from the Pliocene, by the very 

 strong sutural cord. 



Deillia l^vis parva, n.subsp. 



Distinguished from the species by its much smaller size, the broader 

 shoulder, and the slender, short, oblique costse, sometimes reduced to 

 pointed tubercles on the last whorl, their number being twelve to 

 fourteen on a whorl. Diameter 3 "5, height 8 mm. 



Hah. — Near Cuvier Island, in 37 fathoms; type, near the Snares 

 Islands, in 50 fathoms ; Port Pegasus, Stewart Island, in 18 fathoms 

 (Captain J. Bollons). 



Bela Neozelanica, n.sp. PI. VII, Fig. 17. 



Shell small, ovate, solid, slightly turriculate, with blunt axial ribs 

 and spiral lirge, maculated with brown and white below the shoulder. 

 Sculpture consisting of rather distant, low, rounded axial costse, nine 

 to ten on the body-whorl, extending on the spire-whorls from the 

 angle to the suture below, but only over the periphery on the body- 

 whorl ; they are crossed by subequal, flat, spiral lirse, fine on the 

 shoulder, broad upon the base, separated by linear interstices. Colour: 

 the protoconch is flavescent, the other spire-whorls yellowish or 

 brownish white, maculated with brown and white below the shoulder, 

 the ribs usually white, the interstices brown ; body- whorl light brown 

 below the maculations on the periphery ; aperture fulvous inside. 

 Spire conic, turriculate, very little higher than the aperture. Proto- 

 conch papillate, of two smooth convex whorls. Whorls 6, the last 

 high in proportion, with a sloping, broad, and lightly excavated 

 shoulder, slightly convex below the inconspicuous angle ; body- whorl 

 convex, but faintly contracted at the base. Suture distinct, but little 

 impressed. Aperture lightly oblique, elongately oval, angled above, 

 with a rudimentary, broad, and truncated canal below. Outer lip 

 convex, rather thin and sharp, smooth inside, with a very slight broad 

 sinus below the suture. Columella vertical, excavated toward the 

 parietal wall, slightly turned to the left below ; inner lip narrow, 

 thin, spreading over the convex parietal wall, tapering to a fine point 

 below and extending to the base of the canal. Operculum very small, 

 length 2-1 mm., oval, the nucleus apical. Diameter 4-8, height 10 mm
