After a comparison of my original notes on the Lyme sections with a stratigraphical 

 table in manuscript of the same beds, made by my friend Mr. Etheridge, P.R.S., 

 which he has kindly allowed me to examine, I find we are in perfect accordance on the 

 position of the Ichthyolites. Pew remains of this class are found in the Angulatum- 

 zone. The dark marls of the BucJdandi- and Turneri-hed& appear to be the chief 

 repositories of the Lyme Lias Pishes, as already indicated in my sections at pp. 88, 48,
