The teeth in Halicore are more or less cylindrical ; the incisors in 

 their form and wear resemble those of the Hippopotamus. The 

 last molar is compressed laterally, giving the crown a figure-of- 

 eight shape ; but there is no distinction into root and crown. The 

 summits of the crown are tuberculated before wearing ; afterwards 

 they are flattened or slightly concave.
