Anterior (A), and posterior (B), views of left wise true of Leptorycteropus, in which these articulations in both lumbars and posterior dorsals also do not present medi- ally and laterally to the same degree. Five vertebrae are incorporated in the sacrum as compared to six in Orycteropus. The bone is more deeply notched at the junctions of S. 3 and 4. The spines of S. 3-5 are separate at their bases. The centrum of S. 1 resembles those of the presacrals in its flatness and greater width relative to height; that of the last of the series is closer to Oryc- teropus in proportions. The bone is nar- rower across S. 3-4, , the transverse pro- cesses of these vertebrae are relatively less expanded, and the iliac surface is conspicu- ously shallower dorsoventrally relative to its length than in the living form. Insofar as comparison is possible, Cd. 1 is similar to the last pseudosacral (S. 6) of Orycteropus. The other three caudals pre- served progressively increase posteriorly in the lengths of their centra; although other dimensions progressively decrease in the living form, the lengths of the centra re- main nearly constant as far back as Cd. 12, after which a decrease begins. The trans- verse processes of Leptorycteropus arise farther back on the centrum, the neural arches are less notched anteriorly and pos-.
