Abstract
Pebasiconcha immanis gen. & sp. nov, is described from the Miocene Pebas Fo rmation of Colombian Amazonia. Apart from a simple outer lip of the apertur e and a prominent external "mytiloid" thickening shortly below the suture, behind the lip, the genus resembles Strophocheilus. It is the largest terre strial gastropod now known to have ever existed, and one of only two specie s of terrestrial snails recorded from the Pebas Formation. Its shells are a pprox. 20% higher than those of the largest Achatinidae known.
