APPENDIX E. 



REPORT UPON SOME FOSSIL MAMMALIA AND CHELONIA, FROM NEBRASKA. 



By Joseph Leidy, M. D. 



Professor Henry, Secretary Smithsoninn Imtitution : 



Dear Sir: At your request I have prepared the following brief report 

 upon the fossil remains of remarkable Mammalia and Chelonia of Nebraska 

 Territory, a collection of which was transmitted to me by the Smithsonian 

 Institution for investigation and the preparation of a special memoir. 



The fossils were obtained in that portion of country known to the hunters 

 and trappers under the name of "Manvaises Terres," or "Bad Lands." 

 They were collected principally by Mr. Thaddeus Culbertson and Ca])tain 

 Stewart Van Vliet, U. S. A., and were procured for the cabinet of the 

 Smithsonian Institution through the untiring zeal of Prof. Eaird. 



The characters of the remains indicate the locality from which they were 

 derived to be an extensive lacustrine deposit of the eocene period. 



The Mammalian remains consist of one existing genus, Rhinoceros ; one 

 genus known only as extinct, PalcEoiherium ; and seven genera, .SrchcBo- 

 therium, Palceotherium, Oreodon, Me.rycoidodon, Eucrotaphun , Agrio- 

 c/icerits and Arctodon, which are new to Palaeontology. 



The Chelonian remains consist of the two existing genera Testudo and 

 Emys. 



Of Rhinoceros there are two species : 



1. Rhinoceros Nebraskensis, Leidy: Pioc. Acad. Nat. Sciences of 

 Philadelphia, vol. v. p. 121. A species about the size of the R. minutus,
