ternal lobe or festoon of enamel is, however, decisive against its 

 generic relationship with Lopliiodon. 



This indication of the arrangement of the enamel,* slight as it 

 is, reminds one of that in the lower molars of the Toxodon, and 

 another feature of resemblance is the apparent interruption of 

 the enamel at the anterior part of the molar in the fossil. If the 

 presence of two distinct fangs in the Georgian Fossil were adduced 

 as distinguishing it from the Toxodon, it might be replied that 

 perhaps the long curved rootless molars in that animal at the last 

 period of age might, as in the Horse, acquire roots. 



But the trilobed character is on the outside of the molar in 

 question, and on the inside of those of the Toxodon; in which 

 also the middle lobe only has a coat of enamel, not the anterior 

 or posterior of the inner lobes : there is no doubt, therefore, that 

 the Georgian Pachyderm is generally distinct from Toxodon, as 

 it is from Lophiodon ; and it would seem to have diminished the 

 interval which divides the strange Gliriform Pachyderm of South 

 America, from the more normal Tapiroid forms of Pachyderms 

 which are found fossil in the old world. 



As naturalists have accepted the latinized Indian word Tapirus 

 as the generic name of the existing American Pachyderm, which 

 makes the nearest approach to the present remarkable fossil, they 

 will probably sanction the application to the genus and species 

 which it represents, of the name Harlanus Americanus ;f in honor 

 of the indefatigable and accomplished Naturalist by whom the fossil 

 was first made known to Science.
