. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. Fig. 1. Archaeotlierium superbwn, type, No. 9564, right I3, x 1. A, buccal aspect; B, lingual aspect; C, medial aspect. It was also my first impression that this species could best be treated as a nomen dubium, but, inadequate as the type specimen is, detailed comparisons show that it can yield considerable in- formation. Leidy's tentative identification as the right upper lat- eral incisor is fully confirmed, as is Troxell's reference to the ge- nus Archaeotherium. I follow Peterson (1909), Troxell (1920), Sinclair (1922a), and Scott (1940) in separating Archaeo- therium Leidy generically from the European form, whether one prefers to call the latter Entelodon or Elotherium.
