4th lower teeth received into notches in the cranium ; the upper 

 and lower teeth interlocking ; the supra-temporal fossa smaller than 

 orbit ; and the facial profile concave. There are small interdental 

 pits in the cranial rostrum for the summits of the unenlarged man- 

 dibular teeth. 



In the typical T. schlegeli the anterior border of the orbit is not 

 everted ; there are gj teeth ; the mandibular symphysis extends 

 to the loth tooth ; there are only four premaxillary teeth ; and the 

 premaxilla? are not expanded.

R. 797. Cast of the cranium (fig. 10). The original, which is the 

 type, was obtained from a Tertiary (? Miocene) deposit near 

 Eggenburg, Lower Austria ; and is figured by Toula and 

 Kail in the ' Denkschr. k. Ak. Wiss. Wien,' vol. 1. pis. i.-iii. 

 (1885). Presented by Prof. Toula, 1886.
