the rliizome of a Dichjophyllum. Denticulation is visible on a 

 fragment of Cladoplilehis Nebbensis, as in an Austrian specimen of 

 Cladophlebis. The leaves of Gutlieria are coDstantly found with 

 fructification. Sagenopteris, Otenopteris, and Thimfeldia are very 

 I'are. The occurrence of genuine Dichjophyllum 31uensteri and D. 

 Nilssoni may be doubted, the Palsjo specimens of this last species 

 having less regular and shorter secondary segments, although not as 

 short and broad as those of D. acidilobum, Schenk, but perfectly con- 

 cordant with the Transsylvanian Cawpt. Nilssoni. Perhaps the 

 Palsjo species shows transitions to BictyophyUum nigosum, and D. 

 ZecTcenbyi may be admitted as a distinct species under the name of 

 D. polymorphmn. 



The nerves of Nilssonia polymorplm are invariably simple, and the 

 Inmina covers completely the upper side of the rhachis. In all the 

 FterophjHa, from the Trias up to the Cretaceous, the segments are 

 laterally attached to the rhachis, not covering it completely, and a 

 certain number of nerves at the base are dichotomous ; good dis- 

 tinctive generic characters. There are, however, transitional forms, 

 such as Pterozamites Blasii, Bi'aun. Cycadites longifolius, somewhat 

 reminding us of the Chinese Taxites spathulatus, Newb., njay possibly 

 be a Conifer. The least frequent variety of Podozamites distans 

 is the typical form, genuina. Podozamites ovalis, Nath., may be a 

 variety of Podoz. distans. The Strobili of Schizolepis are generally 

 so much worn by rolling that the division of the scales is indis- 

 tinguishable. 



3. Fossil Plants from Eastern Siberia. — By Dr. St. T. Schmalhatjsen. 

 (Imp. Geol. Inst. Vienna, Meeting of January 23, 1 877. ) 



In 1873, Mr. Lopatin, a Eussian Mining Engineer, discovered, 

 among the pebbles of the River Ogux (an affluent of the Yenisei), 

 impressions and casts of plants in fragments of sandstone. The 

 species, as far as they can be ascertained, are : 



Bornia radiata (Brong'.). 

 Filicites Ogurensis, Schmalh. 

 Lepidodendron Veltheimianum, St. 

 Bergeria regularis, Schmalli. 

 „ alternans, Schmalh. 



Lepidodendron WiiManum, 0. Hear. 

 Lepidostrobus gracilis, Schmalh. 

 Knorria, sp. 



Cyclostigma Kiltorl'cnse, Haught. 

 Stigniaria Jicoides, St. 



The presence of Cyclostigma Kiltorlcense proves these remains to 

 have belonged to the Lower Carboniferous. 



4. On the Permian Plants of Funfldrchen, Himgary. — By Prof. 



0. Heek. 

 (Imp. Geol. Inst. Vienna, Meeting of January 23, 1877.) 

 The species found in this locality are: 



Baiera digitata (Brong.) Carpolithes Hunnicns, Heer. 

 TJlmannia Geinitzii, Heer. ,, foveolatus, Heer. 



Voltzia Hungarica, Heer. ,, Eiselianus (Gein.). 



„ BoecJciana, Heer. „ libocedroides, Heer. 



Schizolepis permienn», Heer. ,, Geinitzii, Heer. 



Carpolithes Klockeanus (Gein.). 



They occur in shales, intercalated between brownish, yellowish- 

 grey, and occasionally red sandstones, beneath coarse Triassic quartz-
