1. Sandstones of Groden, between Neumarlct and Mazzon, South Tyrol. 



(Imp. Geol. Instit. Vienna, Meeting January 9, 1877.) 



THE strata here are horizontal in a hill, at the summit of which is 

 Mazzon. Beginning with the lowest beds (near Neumarkt, at 

 the foot of the hill), Nos. 1, 3, and o are grey and red sandy and 

 argillaceous beds of the " Groden Sandstone " ; 2. White sandstones, 

 with vegetable remains ; 4. Subordinate beds of grey shales, with 

 vegetable i-emains ; 6. Yellow dolomitic strata, partly oolitic and 

 glauconitic, and white compact limestones, interspersed with mala- 

 chite ; 7. " Seisser beds," on which Mazzon is situate. 



The plant-remains in No. 2 are indeterminable stems and trunks, 

 with carbonized bark, well preserved and large stohili (of Voltzia 

 Hungarical), branches with acicular leaves, fronds of Ferns, and 

 here and there some few Calamites. The very friable bed No. 4 

 -includes perfectly preserved bracts, acicular leaves, short branches, 

 and strohili. 



Altogether the fades of this Flora is Triassic, like that of the 

 " Eoth " Flora of Zweibriicken. On closer investigation, however, 

 these Flora3 do not possess one species in common. Professor 

 Schimper thinks the Flora under notice to be j)robably of Permian 

 age. Almost all the species are identical with those of Fiinfkirchen 

 in Hungary, which, according to Prof. Heer, are of Post-carboni- 

 ferous or Upper Dyasic age. The branches and strobili of Voltzia 

 Sungarica prevail in number ; Avith them occur Baiera digitata, 

 Heer, Ullmannia Bronni, Heer, Ullm. Geinitzi, Carpolithes, fronds of 

 Ferns, Calamites (or Equisetites) , Lingula sp., some few Fish- 

 scales, etc. 



More or less frequent and distinct fragments of Voltzia Sungarica 

 have been found at several jjlaces in the Tyrol, a fact worthy of notice, 

 as, at these localities, the typical black Bellerophon-limestones (re- 

 presented near Neumarkt by yellow dolomitic rocks) rest imme- 

 diately on the strata containing plant-reinains. The most frequent 

 Foraminifera in the Bellerophon-limestones ax'e Cornusjnrida, es- 

 pecially a form near Endothjra. 



2. On some RhcBtian Plants from Pdlsjo, South Sweden. — By Dr. 



Nathokst. 

 (Imp. Geol. Instit. Vienna, Meeting January 23, 1877.) 

 Dr. E. H. Nathorst lately presented to the Imperial Geological 

 Institute of Vienna a collection of fossil plants from Piilsjo. The 

 species represented in it WQ—Spiropteris, sp., Rhizomopteris SchenJci, 

 Nath., CladopMebis Nebhensis, Brong., Gutlieria angustiloba, Presl, 

 Dictyopliyllum Iluensteri (Gopp.), Nath., Nilssoni. Brong., Nilssonia 

 polymorplia, Schk., Anomozamites ^rac«7zs, Nath., Podozamites distans, 

 Presl, Palissya Brauni. Endl., Schizolepis Follini, Nath., Finites Lund- 

 greni, Nath. (a well-preserved Strobilus), and Swedenborgia crypto- 

 merides, Nath. In a letter to Prof. D. Stur, Dr. Nathorst observes 

 concerning these remains : — Ehizomopteris Scheuki is undoubtedly
