 very closely with those figured by Rutimeyer in the 

 Deukschr. 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, Rut.), described by Filhol 

 in the Ann. Sci. Ge'ol. vol. viii. art. 1, pp. 129, 130. The 

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