Mr. J. A. Douglas, after expressing his gratitude to the

 and had become mixed with a collection from Paracas. 



The speaker considered that the correct identification of these 

 plants was of great importance, apart from clearing up the 

 anomaly in Fuchs's list. David Forbes's statement that nowhere 

 have we evidence of the existence of Carboniferous beds on the
