Type. Detached teeth ; Geological Society of London. 
Teeth very robust, the crown consisting of a median principal 
cone, and two or three large lateral cones on each side. The cones 
are very slightly compressed, though with sharp lateral edges to¬ 
wards the apex, which is acute ; all are marked from the base up¬ 
wards throughout the greater portion of their length with delicate 
longitudinal striae. The summits of the cones are slightly inclined 
backwards, and those of the extreme lateral pair also outwards.
