THE first announcement of the former existence of a 

 small Tapiroid Pachyderm, in the eocene deposits of Eng- 

 land, on the sole evidence of two molar teeth, will not 

 be received without scrupulous examination of its validity 

 by Comparative Anatomists, who know how many and 

 various Mammalia resemble the Tapirs in the configura- 

 tion of the crown of the molar teeth, especially those of 

 the lower jaw, to which the fossils in question belong. 



The proboscidian Dinothere, the marsupial Notothere 

 and Diprotodon, amongst the extinct Mammalia; the 

 Kangaroo and the Cetaceous Manatee amongst the living 

 forms of the class, participate with the Tapirs, both recent 

 and extinct, in having the grinding surface of the molar 

 teeth developed into two principal transverse ridges, as 

 shewn in the fossil molar tooth, fig. 107, a and b. But,
