varied considerably owing to changes in the generic name of its 

 characteristic oreodent, which has been shown by Matthew 37 and 

 Douglass 38 to belong not to Merycochoerus but to a distinct genus 

 named by the latter Promerycochoerus. 



It has been suggested 39 that the sands, gravels and tuffs at the 

 top of the Upper John Day may represent a third faunal sub- 

 division. They are typically exposed on Johnson and Bologna 

 Creeks, on Bridge Creek, and in the upper end of Haystack 

 Valley, and are characterized by numerous remains of Miolabis 

 (Paratylopus) . Until the fauna of these beds is better known 

 it may be best to include them with the Promerycochoems 

 horizon. 



The Total Fauna. — For convenience in reference, a complete 

 list of John Day vertebrate species is appended. The list is by no 

 means a final one, and it is to be expected that numerous changes 

 will be made as a complete revision of the fauna progresses.
