by Marshall (1915, p. 382). The following forms were collected by the writer 

 and determined by Mr. Suter. Recent species are indicated by an asterisk.

In addition to the above, five new species have been described from the 

 same locality by Mr. Suter. These are — 

 Borsonia mitromorphoides Sut. : Niso neozelanica Sut. 



Epitonium gracillimum Sut. ' Vexillum ligatum Sut. 



Euthria callimorplia Sut. 



The greensands from which these fossils were collected are greyish-green 

 in colour and very glauconitic, the glauconite occurring as foraminiferal 

 casts. There is also a considerable quantity of microscopic, subangular, 

 clear quartz. On the Canterbury side of the river these beds form a flat 

 syncline, both limbs showing a dip of 3°, the axis of folding running 

 north by east. Quartz-grits crop out on the bank of the river dipping 

 below the greensands, and farther to the north coal occurs associated 

 with the quartz-grits in a shallow depression on the Canterbury side of 

 the river, this depression being hemmed in by the steep fronts of elevated 

 blocks. On the Otago side of the river the greensands again prove fossil- 

 iferous. The following species were collected on the right bank of the 

 river, near Trig. Station H : —
