A large number of teeth have been found in the Senonian rocks at Oppmanna, 

 and in other localities less abundantly, which present the characteristic appearance 

 of Lamna elegans, Agass., and associated with them are teeth, shorter, broader at 

 the base, and having the fangs of the root more widely separated, which have 

 probably been located in the posterior parts of the jaws of the same species. 

 Anterior teeth elongated and narrow, varying in size, the longest attaining a 

 height of 0'035 m. from the base of the enamelled crown to the point ; the width 

 at the base is 0-007 m. The outer coronal surface is distinctly convex on the 

 lower half, flatter above ; smooth, except a few faint striations at the base ; inner 

 face deeply convex and smooth ; lateral margins produced, very thin, and sharp. 

 The crown is slightly curved, in some specimens scarcely perceptible. The root is
