brought by Mr. Plant from the Province of Rio Grande 

 do Sol ; Zeiller has now added to this list, and furnished 

 additional facts of special value as regards the geographical 

 distribution of Permo-Carboniferous plants. These Brazilian 

 beds have now furnished the following species of plants : — 



Psaronius hrasiliensis, Brong.^ Lepidpphloios laricinus, Sternb. 



Lepidodendron Fedroanus, Carr. Cordaites. 



Noeggerathia obovata, Carr. Gangamopteris cyclopteroides, 



Dadoxylon Pedroi, Zeill. Feist. Etc. 



Odontopteris Phiniiana, Carr. 



In this flora we have, therefore, plants of the same type 

 as those characteristic of Northern Hemisphere Palaeozoic 

 rocks, associated with such a typical member of the 

 Glossopteris flora as Gangamopteris. From plant-bearing 

 beds in the Argentine Republic, Kurtz has recently recorded 

 the following species : — 



Neiiropteridium validum, Feist. Gangamopteris cyclopteroides,Y€\%X.. 



Equisetiies inorenianus, Kurtz. Sphenozaviites inultinervis , Kurtz. 



Nmggerathiopsis Hislopi, Bunb. 



Zeiller - correctly points out that Kurtz's Sphcnozamites 

 is probably a form q{ NoeggeratJiiopsis. He considers these 

 Argentine plant beds are of the same age as those of Rio 

 Grande do Sol, and places both on the same horizon as the 

 Karharbari beds of India, the Ecca beds of Africa, and the 

 Bacchus Marsh and Newcastle beds of Australia. Kurtz's 

 paper has been translated and printed in the Records of 

 the India Geological Stirvey^ and Blanford^ gave an account 

 of the recently discovered Glossopteris flora in Argentina 

 in a short article printed in Nature in 1895. 



The fossil plants described by Geinitz ^ and Szajnocha*^ 

 from x'\rgentina are from younger and older rocks, Rhaetic 

 and Culm, than those containing representatives of the 

 Glossopteris flora. 



In South Africa, India and Australia, undoubted glacial 

 deposits occur in close association with strata containing
