the neighbourhood of Maidstone. In the same group is a small tooth which may 

 possibly be regarded as the third tooth of the upper jaw, closely resembling a 

 tooth assigned to Lamna suhulata by H. Gr. Greinitz (" Palseontogr.," vol. xx., 

 pt. ii., pi. XXXVIII., fig. 31). 



In the Swedish collections the most numerous specimens are obtained from 

 Oppmanna, in the lower stage of the Senonian beds, characterized by the 

 presence of Actimcamax mammillatus, and are now located in the Museum of the 

 University of Lund. In the Danish collections the best locality is Faxe, the 

 Chalk of that district yielding large numbers of teeth in a very beautiful state of 

 preservation. Several of these have been selected for illustration. The Uni- 

 versity Zoological Museum possesses a series from the Saltholmkalk, which formed 

 part of the original museum collected by King Christian VIII. 



Associated with the teeth are vertebrae which in all probability belonged to 

 the same genus.

The teeth which are included in this species are distinguished by the great 

 strength and thickness of the crown, and by the large and prominent develop- 

 ment of the root. The crown is 0-030 m. in height ; the width of the base is 

 0-020 m. ; a lateral extension of the root beyond the width of the crown increases
