MIOCENE FAUNA OF OREGON. 



BY CHARLES H. STERNBERG. 



I propose in this short paper to give a list of the species of mammals and- 

 and turtles collected by my party on the John Day River, and on Bridge creek, 

 of eastern Oregon, during the seasons of 1879 and 1880. I copy Prof. Cope's 

 list published in the bulletin of the U. S. Survey, Vol. 5 No. i, with some of his 

 remarks on new species. These beds are equal to the White River beds of Ne- 

 braska. I have thought this paper might make my article in the January Review 

 more intelligible. For descriptions of species see Palseontological Bulletin, No, 

 30, American Naturalist, December, 1878, and Bulletin above quoted where they 

 are described in detail, by the able paleontologist, Prof. E. D. Cope, of Philadel- 

 phia. All these specimens are in his possession.

 CARNIVORA. — Hoplophoneus brachyops. Cope. 

 Machasrodus strigidens. Cope. 

 Enhydrocyon stenocephalus, Cope. 

 In this new genus and species we observe a nearly complete cranium be- 

 longing to the typical species, the shortness of the facial part of the skull as com- 

 pared with the length of the cerebral, and also the constriction of the skull back 

 of the orbits. The zygomatic arches are robust and expanded, and the sagital 

 crest is high. The auditory bullae are inflated and thin-walled. The length of 

 the skull is about that of the coyote, but it is more robust in all its proportions- 

 except the postorbital constriction. 



Discovered by Charles H. Sternberg in the Oregon White River beds of the 

 John Day River region.
