Some solitary nauplii were found, but tbeir species could not be determined for 

 want of sufficient material. This was also tbe case with a very fevv cells of Peridiniales 

 and varions more or less spherical cells, perhaps ova, Infusoria or only the contents of 

 broken walled individuals. 



A few cells of pollen of foliferous trees and firs had been driven out into the sea. 



After this summary we shall proceed to the discussion of the separate species.
