512 Transactions. — Geology. 



Fossils are very scarce in the bluish-green sandstone, in 

 places quite common in the clays, and very abundant in the 

 hard pebbly bands, which vary from a few inches to about 

 2 ft. thick. At the time of my visit the beach outcrops were 

 sufficiently free from shingle to enable me to ascertain that the 

 fossihferous horizon was only a few yards wide, the bulk of 

 the fossils being contained in one narrow band or shelly sand- 

 stone. 



Stratigraphy. 



The beds are so obscured by beach shingle and recent 

 alluvium that nothing whatever can be made of their strati- 

 graphical relations to the Oamaru Stone and tuffs in the 

 neighbourhood. This information is, however, supplied by 

 the section of Tertiaries exposed at the rifle-butts north of 

 Cape Wanbrow.
