Sagenopteris rhoifolia Presl [S. Nilssoniana (Brgn.) Ward] 

 and a Nilssonia?, both from Rödaisberg. 



Nathorst ^ mentions in the same year some of the fossil 

 plants from Kurremölla, viz. an Anomozamites, a small Equi- 

 setum, fragments of Ctenis, and a small Sagenopteris. 



In Törnebohm and Hennig's ^ description of the geolo- 

 gical map of the solid rocks of Scania several important 

 notes on the coal-bearing formation in the south-eastern part 

 of the province are communicated. Two sections are given 

 which may be reproduced here in order to illustrate the geo- 

 logical structure at the localities yielding the fossil floras.

Our text-fig. 1 represents two sections of the Mesozoic 

 strata at Rödaisberg (Törnebohm & Hennig, 1. c, text-fig. 

 40, p. 114, after observations of Moberg.). In the extreme 

 north-east of section A, the Upper Silurian (Gotlandian) 

 Posidonomya shale is seen, dipping steeply towards south- 

 west and abruptly cut off by a fault-Hne. Immediately S.W. 

 of this fault-line follow almost perpendicular strata of sand- 

 stone and clay belonging to the Keuper. Then follow clay 

 and sandstone beds with a gradually decreasing N.E. dip, 

 belonging to the plant-bearing series. The plant-remains 

 found in the clay close to the Keuper constitute the Flora
