 tively few, very stout, vertical, nearly straight, with fluted enamel, but 

 without carinas ; premaxillse considerably expanded, with three dental 

 alveoli ; orbits directed mainly frontally, and elongated transversely : 

 supratemporal fossae very large and ovoid, with posterior angula- 

 tion ; frontals small ; posterior nares unknown. About 17 upper
