Genus LEPTOBOS, Riitimeyer 1 {ex Falc., MS.). 



This genus, of which representatives occur in the Siwaliks, Nar- 

 badas, and the Yal d'Arno beds, comprises bovine animals presenting 

 strong indications of affinity with Boselaplius. The frontal portion 

 of the skull is very wide, with widely-separated, subcylindrical horn- 

 cores, placed far below the level of the occiput ; the parietal border 

 of the occiput is strongly ridged. The horn-cores are sometimes 

 absent.
