Type. Detached teeth ; British iluscura and Strassburg Museum. 
Teeth moderately robust ; outer coronal face always nearly flat, 
often with large vertical wrinkles; inner coronal face gently 
rounded; root short, the branches very divergent, thick, expanded, 
and abbreviated. Anterior teeth large, triangular, and com- 
paratively broad, the crown only gently curved outwards at the 
apex; lateral teeth having the root much wider than the main 
portion of the crown, which thus exhibits a sudden basal expansion 
behind, and often also in front.
