peculiarity can best be explained, I venture to suggest, by the 

 aforesaid demembration of the original old territory. 



A last question before concluding : Is it probable, in the future, 

 that there may still be discovered in this territory fossils of the 

 Old Paleozoic? Will it be the same with Aequinoctia as with the 

 Jurassic Sino-Australian continent of Neumayr ? 



The numerous explorers who have worked in so many different 

 parts of this region, still so unknown in the time of Neumayr, have 

 succeeded in the course of years in making known, as we have seen, 

 in a fairly continuous series, every period from the Upper Car- 

 boniferous to the Recent. Older fossils have not as yet been 

 discovered, notwithstanding the greatest efforts and the closest 

 attention, and in spite of the fact that the rocks preceding the 

 Upper Carboniferous outcrop in large areas and are frequently 

 deeply cut by erosion, thus offering very favorable points of inves- 

 tigation. Under these circumstances, I suppose that the hypoth- 

 esis of the existence of Aequinoctia during the Old Paleozoic 

 may be maintained.
