" The adder is by far the most common and widely 

 distributed snake in this county. Many instances 

 occur of people and dogs (especially hounds) being 

 bitten by this species. 



"In the two years 1898-1900 I killed six male 

 and five female adders. The males averaged 20 J 

 inches long, the females half an inch longer. The 

 largest male was 24i inches, the largest female 22 1- 

 inches, these being a pair taken together. The small- 

 est male was 13J inches, the smallest female ISh 

 inches, these two also being a pair. Of the eleven 

 adders killed there were three pairs : nine were 

 killed in the month of April, one in May, and one 

 in August.
