TYPE AMMONITES—IV 



Mar. 



Sequence IX — Scotland, East Coast 

 (Upper and Middle Oolites) 



Counties of Sutherland and Ross and Cromarty —  generalized 

 sequence. The succession is surmised in certain cases ; in others it 

 may be known from the relative geographical positions of the strata — 

 much information kindly given by Dr. G. W. Lee (G.W.L.). Specimens 

 were submitted by the Geological Survey of Scotland. 



Only the sequence down to No. 14 is connected with Table III : 

 the remainder will be required later.
