It is remark-able for the abnormality in the structure of the feet, so muchso indeed as to render it for the future unsafe to predict thecharacter of an animal from a single bone, and to invalidate theold maxim, ex pede Herculem. While the proximal bones ofthe feet retain their normal perissodactyle character, thephalanges have been modified to resemble those of Edentates,the second phalangeal bone having a strongly developed distaltrochlea (pulley) for the articulation of the huge claw formingthe terminal joint. These phalangeals have been describedbinder the names of Macrotherium and AncylotheriiLrn, and weregenerally considered to belong to the skeletons of huge Eden-tates. But Dr. Filhol, quite recently, found them in associationwith the skull and
