single nut was 

 of a different 



character from any figured or described to ray knowledge, was 

 found at the horizon of coal 5 at Quinnimont. It is perfectly 

 smooth with no markings, is about 12 mm. long and 5 mm, 

 wide, cylindrical in shape, and bluntly rounded at the ends, 

 one of which is furnished with curved stem-like appendages, as 

 if for attachment. Nuts are quite rare, only these two being 



21. Megalopteris Hartii Andr. In my last visit to the plant 

 locality at Sewell Station, which furnished me on my former 

 visit the specimens of Megalopteris, and which is coal in 9, I pro- 

 cured a few additional specimens of this plant, among which, 

 by comparison with the plates which Professor Andrews has 

 had the kindness to send me, I recognized his M. Hartii Of 

 this plant I have one specimen having the ends of the two 

 leaves at the summit of the frond, showing about six 

 inches of their length. Another specimen shows the termina- 

 tion of a much smaller frond, with three leaves. Along with 

 these leaves I find several of a small Megalopteris which may 

 prove a different species although the nervation, so far as it can 

 be made out in the obscure state of all the plants found here, 

 seems to be very near that of M. Hartii. Of the small plant, no 

 more than two leaves together have ever been found, and no 

 specimen shows the point of junction of these. The small size 

 seems to be a constant feature. Such leaves are about 6 cm. 

 long and 1 cm. wide ; they are narrowly elliptical in shape, 

 with a rather more acute termination than that of M. Hartii. 

 The midrib seems to have been large for a leaf of this size, and 

 very prominent. It leaves a deep rectangular impression. 



22. Megalopteris, species ? This plant is the most common form 

 found at Sewell Station. It differs from all the forms of Pro- 

 fessor Andrews' plants figured in the decided acuteness of the 

 leaves or pinnules ; in which respect it is more like M. Daiu.ioni. 

 From this latter plant it ditlers in the more decided elliptical 

 outline of the leaves, the more rapid narrowing of the leaves 

 toward their extremities, and most of all, in the nervation, which 

 so far as can be made out, is near that of M. Hartii, being fine, 

 from closely placed slender nerves, which fork near the base and 

 again near their middle ; apparently, higher up, than in J/. Har- 

 tii. The nerves are nearly parallel in their coarse ; and curve 

 very slowly outward to meet the border of the leaf. I have 

 one specimen which shows one entire leaflet, and the base of 

 another, which diverges from the rachis at the base of the first, 

 showing the ordinary alternate arrangement on a winged rachis, 

 of the leaflets in plants of this genus. The entire leaflet of the 

 specimen, is 14 era. long, and 2^ to S cm. wide. It is strongly
