The Réunion rail (Dryolimnas augusti) also known as Dubois's wood-rail is an extinct rail species which was endemic to the Mascarenes island of Réunion. The scientific name commemorates French poet Auguste de Villèle (1858-1943) whose interest in the history of Réunion and hospitality made it possible for numerous naturalists to discover and explore the caves of Réunion. As Dubois's account is the only historical reference about the Réunion rail it might be possible that it became extinct in the late 17th century.
