The amphibians and reptiles of the colombian caribbean islands san andrés and providencia

Abstract

In connection with a study of Central America I have examined specimens from many of the islands off the coast, and I here set down a list of those I have seen from two Colombian islands which rise from deep water about 200 km. east of Nicaragua. They are about 100 km. apart. Both represent old volcanic peaks, and it is unlikely that they were ever connected to each other or to the mainland, although they may have been much larger during a lower glacial sealevel. The herpetological fauna of San Andres and Providencia consists Of: a frog, known from both islands; six lizards, three from both islands and three from Providencia; four snakes, one from San Andrés and three from Providencia.
