stones which overlie the coal opposite the lower greensands. 

 The position the vertical fault would occupy in section from 

 the river-bank southward is indicated in fig. 8. 



The seam of brown coal occurs in grey sandstones often 

 yellow on surfaces, and grits, which are exposed in the narrow 

 gorge cut in the foothills by Wharekuri, about half a mile 

 above the bridge. The outcrops of the beds are so obscured 

 by gravels and slope deposits that no stratigraphical relation- 

 ships can be made out. 



Mr. McKay refers the coal-measures to the Pareora series 

 of supposed Miocene age, and in his sketch* of the section, 

 shown by me in fig. 8, he shows the coal-measures and a 

 coal-seam overlying the calcareous sandstone (Otekaike lime- 

 stone) conformably. I could find no trace of the coal- 

 measures, or of a coal-seam in this section overlying the 

 fossiliferous Tertiaries, and I can only assume that the sec- 

 tion figured by him is intended as a graphic representation 

 of his views rather than a statement of the actual facts. 

 Mr. McKay furnishes no evidence in support of a Miocene 

 age for the coal-measures beyond assuming that the coal is 

 associated with the gravels which cover the foothills. Of 

 this latter theory there is no evidence whatever. These 

 gravels are apparently the old high-level gravels formed by 

 the Waitaki Eiver. They can hardly be older than Pleistocene 

 or newer Pliocene. 



Sir James Hector, in his Progress Eeport for 1881, p. xxv., 

 when discussing Mr. McKay's supposed Pareora gravels, 

 says, " These beds, for no better reason than that they are 

 usually found overlying the fossiliferous Pareora beds, have 

 frequently been spoken of as the higher part of the Pareora 

 formation. They have probably no connection with the series 

 of strata with which they have in various reports been asso- 

 ciated." 



Fossils. 



From the shelly sands and soft sandstones of the Mount 

 Brown beds, exposed on the south bank of the Waitaki, half 

 a mile below the junction of the Wharekuri Stream, I made 

 a large collection of fossils, which included the following 

 species : — 



1. Kekenodon onomata, Hector. 



2. Pleurotoma fusiformis, Hutton. 



3. Scaphella attenuata, Hutton. 



4. Scaphella corrugata, Hutton. 



5. Scaphella fusiformis , Hutton. 



6. Scaphella pacifica, Lamarck.
