Mull, Arran, and Ross-shire specimens have been 

 taken as long as 27 and 28 inches." — J. Macknaught

Mid- Lothian. 



" 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. 



Aberdeenshire. 



" 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.
