SUMMARY 



The tapir specimens from the Auriferous Gravels of Cali- 

 fornia and from the marine beds of Cape Blanco, Oregon, both 

 represent species not distinctly removed from the existing 

 Tapir-us (Elasmognatlnis) bairdii. 



The California specimen seems to be near Tapirus haysii, but 

 shows differences which appear to be of at least subspecifie value. 

 This form is tentatively referred to as Tapirus haysii Califor- 

 nia^, n. subsp. 



The Cape Blanco specimen is near Tapirus haysii, and shows 

 indication of relationship to Elasmog nat litis bairdii. It is prob- 

 ably near the form from the Auriferous Gravels, and is referred 

 to as Tapirus, near haysii calif ornicus. 



The Auriferous Gravel and Cape Blanco specimens both seem 

 to represent a stage of evolution quite certainly not earlier than 

 late Pliocene, and probably not older than early Pleistocene.
