Remains referable to the genus Palaeosyops are the most common of those 

 of the larger extinct mammals occurring in the Bridger Eocene formation 

 of Wyoming. The. genus was originally indicated by characteristic spec- 

 imens of teeth represented in Figs. 4, 5, Plate V, and Figs. 3 to 6, Plate 

 XXIII. Subsequently a number of specimens were received from time 

 to time and indicated in the Proceedings of the Academy from 1870 to 

 1872, and in Professor Hayden's Preliminary Report of the Geological Sur-
