Bufo Periglenes

Amongst the Anuran Research papers in Professor Mundeign's catalogue, the Monte Verde golden toad has a prime place (though sadly only within the extinct species section). The Monte Verde golden toad (Incilius periglenes, formerly Bufo periglenes) was a small true toad that was once abundant in a small, high-altitude region about 4 square kilometres (1.5 sq mi) in an area north of the city of Monteverde, Costa Rica. It was endemic to elfin cloud forest. It was first described in 1966 by herpetologist Jay Savage, but the last sighting of a single male golden toad was on 15 May 1989, and it has since been classified as extinct.
