Additional information on Vipera albizona (Reptilia, Serpentes, Viperidae)

Data from 10 specimens of Vipera albizona are being compared with the holotype, the paratype and 3 other specimens. Distinction from other representatives of the Vipera xanthina complex and particularly Vipera wagneri is discussed. It is concluded that the characters of the, on the basis of two specimens, newly described species can be largely confirmed for the greater part by this study and that distinction on the basis of colour and pattern is not as difficult as sometimes is thought.
