LIFE AND WORKS OF COPE. XXxiii 



tions from the John Day, Loup Fork, Blanco, Palo Duro and 

 Port Kennedy Bone Cave. 



As an explorer he had marked success, finding the unique 

 skeleton of Hyrachym, of Loxolophodon, a name which was 

 telegraphed to the American Philosophical Society, and 

 converted by the operator into Lcfalophodon. In the 

 Bridger, Cope himself found the lower jaw of Anaptomor- 

 phus, a little monkey with a dental formula like that of 

 man, which, owing to its extreme antiquity, occasioned 

 him a greater surprise than any discovery he ever made. 

 He also found the last of the great race of Uintatheres at 

 the top of Washakie Mountain of Central Wyoming. We 

 owe to him alone our knowledge of the scanty Wind River 

 fauna. From the White River Oligocene his materials were 

 poor and his work less satisfactory. From the rich Upper 

 Oligocene, with the assistance of Wortman, he secured fine 

 collections and has especially enriched our knowledge of 

 the Aiichitheriidse, Felidse and Canidse. From the Upper 

 Miocene Deep River and Loup Fork beds he has practically 

 contributed all that we know, especially of the Rhinoce- 

 roses, Horses, Mastodons, Camels, and other ruminants and 

 carnivora. Of the latter fauna his most complete papers 

 were upon the evolution of the Oreodontidse. His latest 

 contributions to our knowledge of the fossil Mammalia 

 were upon the fauna of the Blanco and Palo Duro, or Good- 

 night beds of Texas, and the rich cave fauna from Port 

 Kennedy, Pa., brought together by his warm friend. Dr. H. 

 C. Mercer. It was his intention to cover the entire later Ter- 

 tiary in a second part of the " Tertiary Vertebrata ;" many of 

 the plates and much of the MSS. of which volume are ready. 



The " Tertiary Vertebrata," Vol. III., of the Hayden 

 quartos, published in 1883, is his most imposing contribu- 

 tion to paleontology, including his studies of all the verte- 

 brate fauna of the Tertiary lakes west of the Rockies. This 

 work of over a thousand pages and eighty plates is said to
