The classification of our material, therefore, will be approxim- 

 ately as follows: 



A. 



Terrestrial 

 Group. 



Lower part of the 

 profiles or Holm's 

 Land. 



Sandstones and shales with plant-fossils. 



Exposed not more than 200 metres, but their 

 thickness probably amounts to about 500 metres, 

 or possibly more.
