Genus EOTHERIUM, Owen \ 



This genus, which is provisionally referred to the present family, 

 is only known by the type species. 



Eotherium segyptiacum, Owen \ 



Syn. (?) Manaius coulombi, Filhol ^. 



This species is founded on the cast of the brain-cavity, which 

 resembles that of Halitherium and is narrower than in Manatus ; 

 but it appears highly probable that the lower cheek-teeth from the 

 same locality, described under the name of Manatus coulomhi, are 

 specifically identical. These teeth are practically indistinguishable 

 from those of existing species of Manatus ; but the number is 

 unknown. 



Hah. Egypt.
