Description
Original diagnose after Leidy (1877) p. 251-252: The remaining pair of teeth perhaps belong to a different species and genus. The crown is very much smaller in proportion to the root than in the former, and its lateral borders are not denticulated. The tooth represented in figure 35 has a small oblique, demiconoidal crown with a rather wide and slightly recurved summit. The root is of comparatively enormous proportion, and resembles in shape that of ti1e large tooth first described. Length of the tooth from the root notch, 5 lines; length of crown, 1 1/2 lines ; breadth at base, 2 3/4 lines ; length of root, 6 3/4 lines; breadth, 7 lines. The tooth of figure 36 has the crown proportionately larger and the root thicker but narrower, and with bu t feebly developed processes. Length of the tooth, 6 lines; length of the crown, 2 lines; breadth at base, 3 1/2 lines; length of crown at middle, 4 1/2 lines; breadth, 4 lines; thickness, 3 lines.
