43419. Fragment of the left maxilla, containing the three pre- 

 molars ; from the Upper Eocene of the Aveyron Valley 

 (Tarn-et-Garonne), France. The teeth appear to agree 

 very closely with those figured by Riitimeyer in the 

 Denkschr. schw. Ges. Nat. vol. xix. art. 3, pl.ii. figs. 16-20 ; 

 in the distinct V formed by the union of the anterior and 

 posterior ridges they differ from the premolars of L. lautri- 

 ciensis, Noulet (L. rhinoceroides, Riit.), described by Filhol 

 in the Ann. Sci. Geol. vol. viii. art. 1, pp. 129, 130. The 

 length of the space occupied by the three teeth is 0,090.
