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

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

 L. chalaniati heing 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 space 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 third premolar has a well-marked 

 inner cusp, and therefore differs from Tragulus and agrees 

 with Dichodon. Purchased, 1884.
