No fossils were obtained in this formation at its type locality. 

 Doctor MacDonald collected fossil plants at station No. 6840, about 

 7 miles northeast of Bejuca, near Chame, Panama, in a yeUowish. 

 argillaceous sandstone that seems to overlap agglomerates and is 

 beheved to represent the Caimito formation. Professor Berry records 

 the following species from this locality: 



Guatteria culehrensis Berry, also Culebra and Gatun formations. 



Hiraea oligocaenica Berry. 



Hieronymia leJimanni Berry. 



Schmidelia hejucensis Berry, also Culebra formation. 



As two of the four species also occur in the Culebra formation, it 

 appears that the deposit in which they were obtained is in age near 

 the Culebra formation. 



Miocene. 



GATUN FORMATION. 



The principal collections from the Gatun formation were made 

 jointly by Doctor MacDonald and myself at stations Nos. 6029a-6, 

 G030, 60336-f, 6035, and 6036, the position of each of wliich is platted 

 on the map (pi. 154), and the sections are described in Doctor Mac-
