Daphnella aculeata, Webster, T.N.Z.I., xxxviii, 1905 (1906), 306, pi. 38, f. 4. 



Shell fusiform, small, thin and fragile, turriculate, axially finely 

 ribbed and spirally striate, buff-coloured. Sculpture consisting of 

 axial slight diagonal ribs, about 12 on the last whorl, the interstices 

 much wider than the riblets, and ornamented with fine growth- 

 lines ; crossed by 2 to 3 strong spiral keels on the spire- whorls, the 

 first spiral below the shoulder being composed of 2 threads ; body- 

 whorl with about 13 sharp spirals, the upper six more distant than 

 those on the base, and the crossing-points are raised into small gem- 

 mules. The interspaces between the spirals are microscopically spirally 

 striate, the shoulder with crescent-shaped growth-lines. Colour buff, 

 lighter towards the apex and canal. Spire conical, turreted, some- 

 what higher than the aperture. Protoconch of 1^ whorls, convex, 

 papillate, microscopically reticulated. Whorls 5, broadly shouldered, 

 the shoulder somewhat concave, bicarinate below ; body-whorl in- 

 flated, strongly contracted at the base. Suture deep at the proto- 

 conch, well marked further down. Aperture pyriform, broadly angled 

 above, produced below into a straight short canal, truncated ante- 

 riorly. Outer lip thin and sharp, strongly convex and contracted 

 below, with shallow rounded sinus at the suture. Columella straight, 

 slightly twisted and bent to the left below ; parietal wall straight, 

 concave on meeting the columella. Inner lip very thin, the spiral 

 riblets passing over it. 



Diameter, 3-3 mm. ; height, 6 mm. 



Animal unknown. 



Type in the Dominion Museum, Wellington.

3. Daphnella amphipsila, Suter, 1908. Plate 22, fig. 11. 



Daphnella amphipsila, Suter, P. Mai. S., viii, 1908, 190, pi. 7, f. 26. 



Shell very small, narrowly fusiform, thin, white, translucent, 

 smooth. The sculpture consists of a number of spiral lira? on the 

 base, and a few indistinct microscopic spiral lines on the whorls ; 

 growth-lines very fine and dense. Colour white, vitreous. Spire 

 conic, a little higher than the aperture, outlines straight. Protoconch 

 mamillary, of 2 smooth whorls, the nucleus minute, the succeeding 

 whorl rather swollen. Whorls 5, regularly increasing, lightly convex, 

 base contracted. Suture linear. Aperture subrhomboidal, the sides 

 subparallel, angled above, produced below into a somewhat oblique, 

 short but distinct, broad, and truncated canal. Outer lip moderately 

 convex, straightened at the middle, contracted below, smooth inside. 

 Columella straight, excavated towards the flat parietal wall, lightly 

 curved below towards the margin of the canal. Inner lip thin and 

 narrow, smooth. 



Diameter, 1-6 mm. ; height, 3-5 mm.
