DiscusionThere are 195 terrestrial species of snakes. Botriechis schlegeli (Berthold, 1846) is a new registration, from the locality of El Caucho, department of Tumbes. The taxonomic changes, produced at different levels, after the publications of the Catalog of Neotropical Squamata (Petrs & Donoso-Barros, 1970; Peters & Orejas-Miranda, 1970) and from additions and corrections of Vanzolini (1986), are included in the present list. Henle & Ehrl (1991) located our vipers in the family Crotalidae, however, we prefer to continue with the classification of McDowell (1987) and maintain the family Viperidae. Varios vipers included in the genus Bothrop were put in Bothriopsis and Porthidium (Campbell & Lamar, 1989). Our species of Rhadinaea were put in Taeniophallus (Myers & Cadle, 1994). For the genus Chironius continued with Dixon et al. (1993).
