Abstract
A well established natural population of Helisoma duryi (Wetherby) was recently found in central Brazil, where it was introduced probably with aquatic plants conveyed by aquarists. A morphological description based on the observation of 10 specimens is presented, involving the shell, cephalopodal mass, mantle organs, reproductive system and buccal apparatus.
