Of No. 3 Prof. Nathorst remarks that it may be the same as an 
undetermined species from Ireland, described by Baïly——Of No. 4 
he says that one is like Sphenopteris Lebedewi of the Donetz basin in 
Russia and another like Sphenopteridium dissectum of the Lower Car- 
boniferous of Germany. No. 8 he compares to A. fissilis of the Donetz 
basin—No. 11 is like S. tenerrimum, Ettings. of the Lower Carboniferous 
of Germany—No. 19 resembles L. acuminatum Güpp. sp. of the Lower 
Carboniferous. 
This flora of Bear island is of a most interesting kind, whether as 
showing the possibility of productive coal mines in the far North in 
the Devonian age, or because of the composition of the flora and its rich- 
ness in forms of vegetation hitherto unknown. Among the filicoid 
plants perhaps the most notable is Cephalopteris Nathorst.* 
This flora had been first studied by Oswald Heer and later by A. G. 
Nathorst, who with additional material collected by himself and Prof. 
J. G. Andersson made a fresh study and has written the fine memoir 
alluded to above. Dr. Nathorst has presented in great amplitude 
several novel types of vegetation that give a distinct facies to this re- 
markable flora. One species Sphenopteridium Keilhaui, with stem
