Fossil ferns are fairly common, but are seldom found sufficiently 
preserved for specific distinction. The four common genera have 
been found in these strata : — Pecopteris, Alethopteris, Spthenojjteris, 
and Xeuropteris. 
The fossils herein mentioned, from the Hard Bed Coal-balls, 
are ordinary casts. Those showing structure are reserved for 
a future paper. 
Note. — With a few exceptions all the above specimens, most of them 
being in my cabinets, have been seen by Mr. Kidston, F.G.S., and the species 
confirmed by him
