Abstract
The genus Dendrerpeton was established by Owen on the evidence of remains found by Sir C. Lyell and the writer in an erect tree at the South Joggins in Nova Scotia in 1852. Other specimens were afterwards obtained, and the most complete, presented by me to the Cabinet of the Geological Society, was found in 1861, and described in my “Airbreathers of the Coal Period.” These remains rendered it certain that the animal belongs to the order Labyrinthodontia, and it is regarded by Lydekker as the type of a family in that group.
