above is almost throughout of real Carboniferous character, and 

 many species are identical with those from the lower Coal-seam ; 

 but some few species of the Niirschan Gas-coal seem to bear Per- 

 mian affinities. 



1 enumerated all the plants in my papers above mentioned, and it 

 will be sufficient to mention the genera only, and some of the species. 



Plants in the Gas-coal} 



Calamites (3 sp. Carbonif.), Huttonia, Asterophyllites (Carbonif.), Sphenopliyllum 

 (Carbonif) . 



Sphenopteris' (about 9 Carbonif. sp.), Hymenophyllites, Schizopteris^ Cyatheites (4 

 sp. Carbonif.), Alethopteris (3 sp., important, Alethopt. erosa, Gutb., and 

 longifolia, Gopp.); Oligoearpia (?), Neuropteris, Odontopteris (I tbink obtusi- 

 loba, Naum., or obtusa, Brong.); Bictyopteris Brongniarti^ Gutb.; Cyclopteris. 



Lepidodendron dichotomum, Stbg. ; Sagenaria elegans, Stbg. ; Knorria, Lepidophyllum 

 ■ majus, Brong. ; Lepidostrobiis variabilis, L.H. ; Cardiocarpon, etc. 



Sigillaria distans, Stbg. ; Sigillarinestrobus^ Stigmaria. 



Walchia — I tbink certainly some brancblets belong here (of the common Permian 

 form). 

 There are, altogether, about 50 species of plants of Carboniferous 



character, besides the animals, which Dr. Fritsch, from the very 



first,^ recognized as Permian genera, and which he lately announced 



before the Glasgow meeting, as representing the passage between 



the Carboniferous and Permian formations. 



h. Plants in the Shale above the Upper Seabi.* 



As in the Gas-coal, and also in the Shale above the UiDper Coal- 

 seam (therefore also above the Gas-coal), the Flora is still of 

 Carboniferous character. I had occasion to determine about 75 

 species, mostly well-preserved and interesting plants. All orders, as 

 ^quisetacecB, Filices, Lycopodiacece, and Sigillarice, are frequently 

 represented; Sphenophjllum Schlotheimi, Brong., very frequent, SpJie- 

 nopteris abounds, amongst which truly Carboniferous forms, as 

 Sphenopt. Moningliausi, Sph. obtusiloba, Brong. ; Sp)Ji. asplenites, Gutb., 

 prevailing; Neuropteris numerous; Adiantites giganteus, Gopp.; 

 Bictyopteris, Gutb. ; Cyatheites, Aletliopteris, and especially various 

 forms of fern trunks of the genus Megapliytum, which I described in 

 a special paper.^ 



Lycopodites, Lepidodendron, Sagenaria, Bergeria, etc., all very 

 frequent. 



Sigillaria very abundant, wdth about ten species, and Stigmaria 

 throughout. 



With these plants from the Shale above the seam, the Niirschan 

 Gas-coal has more than the half of its species (about 32) in common, 

 and in both strata the Flora is to be considered as a continuation of 

 that in the Lower Coal-seam.
