a quarter and half a mile from the beach. The strata are dipping about 

 3 degrees to the east. Their actual stratigraphical position is not clear in 

 the stream itself, or on its banks, but it is generally admitted that at the 

 rifle butts, a mile and a half distant, they rest conformably on the green- 

 sands which Park probably rightly correlates with the Hutchinson Quarry 

 beds— that is, the Upper Eocene of McKay. These greensands rest con- 

 formably on the limestone, though Park differs slightly from the last 

 opinion, and maintains that the beds in reality lie between two limestones, 

 the upper of which is not represented in this section, but, if present, would 

 overlie the Awamoa beds. We have failed to see any evidence of this in 

 the district. A collection of fossils was made with considerable care from 

 the Awamoa beds during several days, but it does not pretend to be ex- 

 haustive at present. Nearly all the identifications have been made by Mr. 

 H. Suter.

Hutton, in the " Geology of Otago," 1875, and in the Trans. Linn. Soc. 

 N.S.W., mentions fifty-seven species, almost the same number as in this 

 list, but only twenty-two are identical, even when allowance is made for 

 synonyms. It is probable that his Awamoa list included specimens from 

 other localities near Oamaru, for he states that the formation extends
