Lophiodon parisiensis, F. Gervais '. 



Gaudry (' Les Enchainements, &c. Mammiferes Tertiaires,' p. 69) 

 includes in this species the smaller specimens from Cuyse. It 

 appears doubtful if L. medius. Fischer (' Synopsis Mammalium,' 

 p. 413 [1829]) is really distinct 2 . The species is somewhat smaller 

 than L. isselensis.

M. 2629. Fragment of the right maxilla, containing m. 2 and m. 3 ; 

 from the Lower Eocene of Cuyse-la-Motte, near Epernay 

 (Marne), France. The teeth agree very closely with those

2 The type of this species is the upper molar from Argenton, figured in the 

 ' Ossemens Fossiles,' 2nd ed. vol. ii. pt. i. pi. x. fig. 9. Rutimeyer (Denkschr. 

 schw. Ges. Nat. vol. six. art. 3, pi. iii. fig. 30) figures under this name a molar 

 agreeing very closely in size with the types of L. parisiensis ; while under the 

 latter name (fig. 27) a much larger tooth is figured.
