The dental series is slightly arched. [...] I know from the mandible a fragment of the left horizontal ramus, with the last two premolars and the first true molar. Each cheek tooth consists of two almost equal and elliptical prisms, just a little narrower on the inner side, with its greater diameter in transverse direction. The p3 has
