“The adder is the most common ophidian in this 
county, but is not frequently seen—perhaps more 
often on the Pentland Hills than elsewhere. Its 
average length in the county is 24 inches. The ring 
snake does not occur, and the smooth snake is not 
recorded. I have seen fourteen adders in different 
parts of Scotland, the smallest measuring 22 inches, 
the largest 27 inches. The smallest was captured on 
the Ochil Hills near Dollar, and the largest at Zenga, 
in the island of Mull.”—A. B. Steele, 41 Regent 
Street, Portobello.

“The adder is the only snake of this county, and 
is locally termed the grey adder. It is found in fair 
abundance, growing to a length of 24 inches.”—John 
Davidson, Marischal College, Aberdeen.
