Teeth medium size ; median cone of anterior teeth high, robust, in form of 

 isosceles triangle ; point slightly recurved outwards ; height of large example 

 0"030 m. ; breadth at base of cone 0*017 m. ; outer coronal surface slightly convex 

 or flat ; median basal portion depressed, with or without grooves ; inner coronal 

 surface convex, smooth ; lateral margins constitute a sharp cutting edge. Single 

 pair of divergent lateral denticles broad, compressed, pointed ; breadth of base, 

 including lateral denticles, 0-030 m. Postero-lateral teeth as broad as long ; 

 median cone more or less triangular ; lateral denticles larger comparitively than 

 those of the front teeth. Root larger, with deep lateral prongs ; external surface 

 depressed and hollow ; internal one prominently convex. 



In the collection sent from the Zoological Museum at Copenhagen there are a 

 large number of teeth from the Chalk of Faxe which undoubtedly belong to this 

 species. Associated with them are still larger numbers without lateral denticles.
