which he named Liversidgea oxyspora, and remains of Ptcris 

 from the same beds.* 



Thus closes my very cursory glance over one of the niost 

 fruitful and useful fields of research for Australian workers. t 

 It will be seen that our pahTobotany has not been entirely 

 neglected, but as yet the ground has only been ploughed in 

 certain promising areas, a preparation of fallowing which w'ill 

 surely produce good palaeobotanical crops to be harvested by 

 the comJng generations of students of ancient plant-life.
