Hurron.—On new Tertiary Shells. 817 
Clathurella (?) nexilis. Pl. xviii., fig. 9. 
Shell minute, fusiform, cancellated. Whorls 6, the two first embryonic, 
polished ; the others angled. Those of the spire with a prominent spiral 
keel crossed by rather oblique and rather distant spiral threads, forming an 
obtuse angle on the keel. Suture margined. Body whorl with 8 or 9 
spiral ribs, the first and third larger than the others ; all after the sixth very 
close together on the canal; these are crossed by rather distant longitudinal 
lines which form a very obtuse angle on the first spiral rib or keel ; aperture 
less than half the length of the shell, rather constricted and angled behind : 
columella straight, produced into a short canal. 
Length, :17 inch. 
Locality. Wanganui and Petane. 
Apparently near to C. tricarinata, Val., perhaps it should be considered 
as a species of Drillia. 
Daphnella protensa. 
Shell elongato-fusiform, with the spire longer than the body whorl, 
rather thin. Whorls 7, the first 21 embryonie ; the others ornamented with 
delieate spiral threads crossed by growth-lines ; those of the spire rounded 
more or less longitudinally plicated; about 15 plications ina whorl. Suture 
well marked. Aperture oval, the anterior canal broad and short; posterior 
sinus small but well marked and giving rise to a series of curved growth- 
lines on the posterior portion of each whorl. 
Length, ‘83 inch; breadth, 1 inch. Aperture, :15 inch. 
Locality. Petane. 
Daphnella lacunosa. 
Shell minute, sub-fusiform. Whorls 5, the first two embryonie, polished ; 
the others slightly rounded, with strong spiral ribs at equal distances. Spire 
whorls with 8, body whorl with 10 or 12 of these ribs ; the grooves are rather 
broader than the ribs and are smooth or very slightly longitudinally striated. 
Suture well marked. Aperture ovate, about half the length of the shell; 
the posterior sinus obsolete: anterior canal short ; outer lip thin. 
Length, :18 inch. 
Locality. Wanganui. 
Natica ( Ampullina) levis. PI. xviii., fig. 10. 
Shell sub-globose, transverse, smooth, without any spiral markings. 
Whorls 4, the two first polished. Aperture broadly ovate, rounded in front; 
columella curved, the callus covering the umbilicus. Cee, 
Length, -78 inch; breadth, :9 inch. Aperture, length, ‘67 inch; 
breadth, *5 inch. 
Locality. Wanganui and Petane.
