For comparison with the above we tabulate in a similar manner 

 the list of fossils obtained by Prof. N. S. Shaler, from the north- 

 western part of the Dismal Swamp, near Suffolk, and identified by 

 Dr. Dall. We take the list from Prof. Shaler's monograph on the 

 Dismal Swamp in the Tenth Annual Report of the United States 

 Geological Survey, page 315.
