There is one record of albinism in the Prairie Ringneck Snake. Earle (1958) stated that a female albino ring-necked snake, Diadophis punctatus arnyi, 322 mm in total length was collected near Alma, Wabaunsee County, Kansas, in July 1957 and received by the Museum of the University of Colorado (UCM9861). The first record of an albinistic Northern Ringneck Snake was reported by Cooper (1958). Cooper described an adult specimen found under a flat rock beside a rocky stream bed on the outskirts of Bayrd, West Virginia, by Glen Griffin on 29 May 1954 as being white with a yellowish ring around its neck. It was deposited in the collection of Charles J. Stine of Baltimore. Hensley (1959) and Bradshaw (1966) sub- sequently listed this record. Hensly added Anne Arundel County to the locality but Bradshaw sug- gests "Bayard, Grant County, " West Virginia is the proper locality. Bradshaw (1966) recorded a juvenile 149 mm in total length, found in a wooded section along the rocky stream course of Falling Run, in Morgantown, Monongalia County, West Virginia in October 1965. He stated that the complete absence of melanin and other pigments was evident from the pink colour of the body, the iris of the eye, and the tongue. Only the ring at the base of the head suggest- ed pigmentation and was faintly distinguishable
