CLASSIFICATION 5 



a place can best be found for them as a very highly developed type 

 of alga. Their internal morphology would ally them closely with the 

 more advanced members of either the Chlorophyceae or the 

 Phaeophyceae. The only reproduction so far recorded is that of 

 spores which were developed in tetrads, and therefore may have 

 been akin to the Rhodophycean or Phaeophycean tetraspores.
