If from the 76 species recorded in the above Table vre deduct 21 

 species as being peculiar to the locality, i. e. not found elsewhere in 

 Britain or the continent of Europe, and 10 others that are not 

 found elsewhere in British Devonian rocks, making 31 in all, we 

 have only 45 species left for comparison with other British localities.
