“The ring snake is the most common here, averag- 
ing about 16 inches long, but one was taken near 
Darlington in 1895 measuring 21 inches. This snake 
frequents the lower lands. The adder, which is in-

about 22 inches.’—George Best, Bondgate, Dar-

most common in this district (York). I have seen 
it frequently on Strensall Common, varying in 
length from 15 to 27 inches. The ring snake is 
not so often met with, but I have seen them about 
3 feet in leneth.’—Robert Dutton, Phoenix House,
