species. The collection contained about 68 species from four localities, viz., 
White Rock River ; Mount Harris ; Point Hill, Waitaki ; and from the green 
sands at Waiho. Of these 22 are additions to our tertiary fauna. The 
remainder are species already described as found in our tertiary rocks, and 
from them I judge that the whole collection belongs to the Pareora forma- 
tion, lam the more confident of this determination as six of the species 
here described as new are also found in the Pareora formation at Awamoa 
and other places in Otago. It is worthy of notice that Pecten hochstetteri 
was in the collection from Waiho, showing that this speciesis not exclusively 
characteristic of the Oamaru formation. 
TYPHIS HEBETATUS, sp. nov. 
Plate XVI., Fig 1. 
Ovato-fusiform. Whorls, seven, irregular, smooth. Varices four in a 
whorl, rounded, spines obsolete. Tube for excurrent canal, short, conical. 
Aperture, oval. Anterior canal, closed, short, flattened. Axis, 1:1.

FUSUS DENTATUS, sp. nov. 
Elongato-fusiform. Whorls, eight or nine, sub-carinated, with distant, 
low, spiral ridges, crossed by low, rounded, transverse ribs, which on the 
keel are produced into flattened sharp teeth. On the body whorl there are 
three of the low spiral ridges posterior to the keel, while anterior to the 
keel the second or third ridge is rather larger than the others, and is fol- 
lowed by about 20 more on the produced canal. Aperture, broadly ovate, 
suddenly narrowed into the canal, which is much produced, narrow, quite 
straight, and as long as the Spire. Axis, 1:45, Breadth, :5. 
Locality : Mount Harris. 
Allied to F. cumingi, from China, but much narrower, and without the 
fold on the inner lip. 
FUSUS TEGENS, sp. nov. 
Small, elongato-fusiform. W horls, seven, carinated, and with a row of 
tubercles on the keel; about eleven tubercles on the body whorl. Spire 
whorls and posterior portion of body whorl, smooth, shining, but slightly 
marked with oblique lines of growth. Anterior portion of body whorl with 
eight or ten low, rounded, spiral ribs, crossed by about ten sub-obsolete 
varices. Anterior portion of canal, smooth. Aperture ovate, gradually 
tapering into the long narrow canal, which inclines to the left and very 
slightly backward. Axis, +4. Breadth, +17.
