the marine faunas and the terrestrial faunas and floras. The floral 

 evidence as previously stated is inconclusive. I should not, however, 

 be inclined to consider any of the fossil plants, except one Eocene 

 species, described in the present report as younger than Burdigalian 

 nor older than Sannoisian (Lattorfian).

BOTANICAL CHARACTER. 



The fossil flora at present known from the Canal Zone is extremely 

 limited and entirely too small for either purposes of adequate cor- 

 relation or for deductions concerning the true botanical f acies or the 

 environmental conditions. Seventeen species are determined and 

 two or three additional forms are tentatively recognized. This 

 paucity is especially to be regretted since it is improbable that under 

 the existing climatic conditions as favorable opportunities for the 

 discovery and collection of fossil plants will ever be presented as 

 during the digging of the canal. While fossil plants were nowhere 

 found to be abundant in the shales, nevertheless, it is very probable 

 that an experienced collector by working over a large amount of
