Abstract: During a study of adders ( Vipera berus) in Wyre Forest, a systematic method was developed to identify individuals in the field. It was revealed that no two adders possessed identical head markings. It was shown that a photographic record was a re liable aid to identification. Furthermore it was observed that over the period of studv adders retained their individual head markings.
