Rh The tooth, the first specimen found, is represented in figure 4, below. It is the last upper molar of the right side, and is in good preservation. It indicates a fully adult, but not very old, animal. The crown is subtriangular in form, with the corners rounded, and the narrowest portion behind. The antero- posterior diameter of the crown is 11⋅3mm, and the transverse diameter 15⋅3mm. The grinding surface of the crown is concave, and less rugose than in existing anthropoid apes. The diverging roots are a simian feature.
