Abstract: Eleven species of endemic land reptiles inhabit the Cananan archipelago . 4 species of lizards, 3 species of skinks and 4 species of geckos Four species of sea turtles and another introduced species (two frogs and one gecko) complete the list of reptiles and amphibians in the Canary Is- lands The differences between the extant and the extinct herpetofaunas are revealed, with empha- sis on the possible role of man in the extinction of some types of large-sized lizards Actually, Ga- llotia szmonyz 1s the most threatened reptile species in Spain as a whole, followed very closely by the Fuerteventura skmk, Chalczdes simonyz The remaining populations, except for those found on the small islets and rocks, can be considered as not threatened An outstanding feature of the Cana- nan herpetofauna is the fact that Gallotza stehlinz, the Gran Canana giant lizard, is the largest lacer- tid lizard living today, reaching over 26 cm of snout-vent length

Key Words: Distnbution, Herpetofauna, Canary Islands

Resumen: Once especies de reptiles terrestres endémicos viven en el archipiélago canano 4 especies de lagartos, 3 especies de eslizones (o lisas) y 4 de gecos (o pennquenes) Cuatro especies de tortugas marinas y otras especies introducidas (un geco y dos ranas) completan la lista de reptiles y anfibios en las islas Cananas Las diferencias entre la herpetofauna actual y la extinguida son seña- ladas, enfatizando el posible papel del hombre en la extinción de algunas formas de lagartos de gran tamaño Actualmente Gallotza szmonyz es la especie más amenazada de reptil en España, se- guida muy de cerca por la lisa de Fuerteventura o lisneja (Chalczdes szmonyl) Las restantes pobla- ciones, a excepción de aquellas que se encuentran restringidas a pequeños islotes o roques, no se encuentran amenazadas por lo general Una notable peculiandad de la herpetofauna canaria es el hecho de que el lagarto gigante de Gran Canana (Gallotia stehlznz) es la mayor especie viviente de toda la familia de los lacértidos, alcanzando más de 26 centímetros de longitud corporal
