M. 2704. A right upper cheek-tooth, -with the upper end cut and 

 (Fig.) polished ; from the Ited Crag of Bawdsey, Suffolk. De- 

 scribed and figured by Owen in the Quart. Journ. Geol. Soc. 

 vol. xii. p. 233, tig. 12, where it is provisionally referred 

 to E. plicidens. The form of the anterior " pillar " is like

 impossible that the specimen belongs to the former species. 

 Presented by Sir 0. Lyell, Bart.
