like the corresponding superior teetli, except that the lieel of the tlhrd i.s not 



so wide, and the median edge is more prominent. The remaining four molars 



are alike. They consist of a principal conic lobe with a small anterior basal 



lobe and a large posterior heel. The cone has a low median anterior edge, 



and more prominent median posterior edge. The lieel has an obtuse cutting 



edge, which rises in a compressed trihedral form, as it is truncated behind as 



well as flattened at the sides. No cingula on the inferior molars. Enamel 



obsoletely rugulose.
