and L. yaudryi. The length of the space occupied by the 

 three true molars is 0,027, the corresponding space in 

 L. chalaniati being 0,041 (vide supra, p. 162). The man- 

 dible of L. gaudryi (vide Filhol, Ann. Sci. Geol. vol. viii. 

 pi. xiii. fig. 280) indicates a considerably smaller species,

the length of the sp^ce occupied by the three lower pre- 

 molars being only 0,017. The present specimen agrees 

 with L. chalaniati in the abortion of the second inner 

 crescent of m. 3, and in the incomplete development of the 

 same part in m. 2. The thira-premolar has a well-marked 

 inner cusp, and therefore differs^om Tragulus and agrees 

 with Dichodon. Purchased, 1884.
