Of these 14 forms, several — such as the flower AntholUhus. the 

 fern Blechnum^ the grass fragment Poacites^ the leguminous leaflets 

 Leguminosites and Sophora and pod, and the supposed fragment 

 of a cycad pinnule {Zamia) — are the sort of things dependent for 

 their presence as fossils largely on accidents of preservation, and 

 therefore they are of slight value in questions of composition, 

 ecology, or age. 



The following 21 species, or half the total number known from the 

 Miocene of Venezuela, are not known from other regions :

Some of these, as the Inga^ Persea., Poacites^ and Zamia (?), are of 

 slio-ht significance because of incompleteness, and the first three rep- 

 resent widespread types. 



Twenty-three of the 40 species recorded from the Miocene of 

 Venezuela have been found at but a single Venezuelan locality, al-
