Type. Detached tooth. 
Teeth very robust, the crown sometimes attaining a height of 
nearly 0-05. Outer coronal face slightly convex, generally uneven ; 
both the inner and the outer face with a more or less prominent 
series of vertical wrinkles towards the base, usually irregular. A 
single pair of large acuminate lateral denticles, slightly divergent, 
often incompletely separated from the principal cone. Boot with a 
considerable inward prominence immediately below the base of the 
crown.
