which is either uppermost Aquitanian or Burdigalian, and since 

 one of the associated Mollusca is common to the Bowden beds of 

 Jamaica, which are imquestionably of Burdigalian age, and others 

 of the MoUusca are closely related to lower Miocene forms from 

 Trinidad or from Chile, I am disposed to consider this Peruvian 

 fossil flora as Burdigalian in age, and I would extend this correla- 

 tion to the Navidad beds of Chile except for the reason that the latter 

 beds appear to represent more than a single horizon, although they 

 are in part of this age, and in part probably represent older Tertiary 

 horizons. 



I hope to publish an analysis of all of the South American Ter- 

 tiary floras in the near future, and will only say at this time that the 

 flora found in the Loja coal basin in the Ecuadorian Andes is also of 

 Burdigalian age.
