The tooth represented by the figure indicated above is the only one occurring 

 in the collections examined. It is from the Zoological Museum of the University 

 of Copenhagen, and was obtained from the Cretaceous formation at Rugaard, near 

 Grenaa, in Jutland. The tooth is strong and robust ; the crown is 0'03 m. in 

 height; the width of the base of the crown is 0'033m., of which one-third is 

 occupied by the lateral denticles. The outer coronal surface is moderately convex 

 and smooth ; the inner face is well-rounded and also smooth. The lateral 

 margins and apex thin out to a fine cutting edge. Lateral denticles, one on each 

 side, are broad, smooth, and acuminate. The root is very thick ; and on the inside 

 the median portion forms a prominent and expanded boss ; the outside retreats
