HISTOKICAL SKETCH.

Camithcrs, 1 ia 1869, described three new species from the 

 basins of Candiota and Jaguarao, in the province of Rio Grande 

 do Sul. 2 



Odontopteris Plantiava, sp. nov. = Neuropteridiim validum, Feist. 

 Flemingites Pedroanus, sp. nov. = Lepidodendron Pedroanum (Can - .). 

 A'oeggerathia obovata, sp. uov. = Gangamopteris cgclopteroides, Feist. 



These determinations were revised by Zeiller 3 in 1895, who 

 pointed out the identity of some of these fossils with members of 

 the Permo-Carboniferous flora of India. 



In 1870, Plant 4 made the somewhat doubtful record of Lepido- 

 dendron in association with Glossopteris from the same coalfields. 

 Hartt 5 also stated that a specimen greatly resembling Asterophyllites 

 (C'alamoeladus) had been found in the southern portion of the 

 province of Bahia. 



In 1872, Liais 6 showed that Sphenopteris and Calamitean remains 

 occur in the Candiota and Jaguarao Coalfields. 



In 1888, Derby,' Director of the Geological Section of the 

 National Museum, Rio de Janeiro, in a letter to Waagen, after- 

 wards published, stated that Coniferae of the Dadoxylon type with 

 stems and leaves of Lepidodendron, and fragments of Psaronius, 

 have been found in the province of Sao Paulo. 



Renault 8 also described a new species of Lycopodean stem as 

 Lycopodiopsis Derby i, from the coal - basin of Piracicaba, in the 

 province of Sao Paulo. This plant was associated with trunks of 

 tree-ferns (Psaronius) and of Cordaites. Zeiller 9 has suggested 

 that Renault's Lycopodiopsis is a true Lepidodendron, and may 

 possibly be a petrified specimen of Lepidodendron Pedroanum (Can - .). 



In a short series of notices published in 1891, Hettner 1 " 

 announced the discovery of representatives of the Glossopteris 

 flora in a coalfield on the river Jacuhy, known as Arroyo dos 

 Ratos. Zeiller, 11 a few years later, examined these specimens,
