312 M. R. Thorpe — A Newly Mounted Eporeodon. 



and so stated in varions faunal lists.^ The less well pre- 

 served skull and jaws of No. 13119 were replaced in the 

 present mount by the homologous parts of the more com- 

 plete but somewhat smaller cotype, No. 13118. All of the 

 remainder of the mount is of the one individual, the few 

 missing parts being restored in plaster mainly from 

 equivalent parts of the cotype. 



The vertebral formula is C 7, T 13, L 6, S 4, and 

 Cy 20+. This is not the typical formula found in Mery- 

 coidodon, but it would be very apt to vary a^ it does in 

 8us. Undoubtedly there were more than twenty caudals, 

 but this number is all that were collected with the speci- 

 men. The four sacrals and the first sacro-caudal are 

 ankylosed. No complete ribs now pertain to the skeleton, 

 so these have been restored, as well as the superior part 

 of both scapulae, part of the pelvis, all of the sternum, and 

 the right metacarpals and phalanges. Nearly all other 

 parts of the skeleton are present in an exceedingly well 

 preserved condition, even to the sesamoid and pisiform 

 bones. 



So far as the author is aware, this is the first specimen 

 of the genus to be mounted. Skeletons of Merycoidodon, 

 Leptauchenia, Plienacocoelus, P r ornery coclioer us, Agri- 

 ochoerus, and other allied genera are on exhibition in vari- 

 ous museums in the east, but up to the present none of 

 Eporeodon. The skeleton as mounted is 47.5 inches 

 (1.206 m.) in length and stands 17.75 inches (.452 m.) 

 high at the shoulder.
