1. Caudoniferous Flora.

This oeeui's in tho upper member of I lie Carboniferous system of 

 Nova Scotia and Prinee Edwiii'd Island, originally named by tho 

 ■writer tho Newer Uoal-formalion, and more reeently tho I'ermo- 

 Carboniferous, and the upper lieds of which may not improbably be 

 contemporaneous with tho Ijower Permian or Lower Dyas of Europe. 

 In this formation there is a iiredominaneo of red sandstones and 

 shales, and it contains no productive beds of eoal. lis fossil plants 

 are for the most i)art of spceics found in the Middle or Productive 

 Coal-foi'mation, but are loss numerous, and there are a few new forms 

 ttkiii to those of tho European Permian. Tlio most eharaet-eristio 

 species of the upper portion of the fornmtion, which has the most 

 decidedly i\-rmian aspect, are the following:
