poleobotanist, professor R. Zeiller, examining the collection of the 
Countess d’Eu in Paris and the Hetiner collection from the. Berlin Mu- 
seum. In the latter he recognized Gangamopteris cyclopteraides var . 
attenuata, a typical representative of the Glossopteris flora. As the 
result of the study of these collections, both of which came from the, 
Arroio dos Ratos mine, Zeiller reports the presence, accompanying the 
coals in the State of Rio Grande do Sul of; 
(1) Lepidophloios laricinus, a representative of the northern Permo- 
Carboniferous flora ; 
(Il) cortical fragments of large trunks of a true Lepidodendron 
to which he specifically refers Carruthers, Flemingites Pedroanus ; 
(Il) obscure fragments, cautiously and with much doubt referred 
to Stigmaria, another northern type , 
(IV) Gangamopterts cyclopteroides var. attenuata ; 
and (V) a remarkable fossil gymnospermic wood with large 
triradiate pith and small round pores, from the valley of the 
Jaguarao, described by himi as Dadozxylon Pedroi. 
Renault’s Lycopodiopsis Derbyi, noted above, Zeiller (1) regards 
as probably the petrified axis and abraded cortex of Lepidodendron 
Pedroanum. Ve also illustrated a type of megaspore which he thinks 
should belong to Sigillaria, two forms of lepidophytic microspores, one 
spore type possibly lepidophytic, and a gymnospermic form of pollen 
grain. 
The coals of the stale he refers.to the Upper Stephanian or the 
Permian of the Northern Series, and to the Karharbari of the Gondwana 
series. Zeiller’s very important contribution is especially interesting, 
since is the first to point out the intermingling, in the coal fields of 
Southern Brazil, of elements of the Permo-Carboniferous of the Nor 
thern Province with representatives of Lhe Luwer Gondwana or Sou- 
thern Permo-Carboniterous flora, 
However, the greater part of the evidence for the latter was, it 
must be observed, furnished by the coal fields of Argentina, which 
will next be briefly considered. 
A discussion of the discovery of Permo-Carboniferous plants in 
Brazil and of the important conclusions drawn from the peculiar floral 
associations there present, cannot logicalliy be carried forward without
