relic. 



The tooth is remark- 

 ably curved for a ceta- 

 cean. It is rather rough, 

 and is somewhat quad- 

 rate or angular. This 

 character, according to 

 Prof. Leidy, is not con- 

 stant. Its transverse 

 section is rather ovate, 

 with the anterior part 

 flattened. It was point^ 

 ed, but by exposure the 

 apex is injured. Its 

 base has a short conical 

 pulp cavity, less than 

 one inch in depth. Its 

 surface is marked by 

 longitudinal cracks. 

 The tooth belongs to the 

 right lower jaw, and is 

 drawn the natural size. 

 It is supposed to be- 

 long to the miocene, but the locality contains a few small fos- 

 sils, derived from the eocene, and hence this may be of that 

 age.
