Connected also with Cyatheites is the fig. a, on plate XXXVI. 
This has the foliage usually attributed to C. arborescens (the 
Pecorreris arborescens of Brongniart, tab. CIII. fig. 2 and 
3) ; but it will be seen that the stem resembles that of a Lepi- 
dodendron. The figure is very correct. The only observation 
I shall venture at present is, that it appears to me rather to 
belong to Conifere than to Filices. This is from Pictou, 
Nova Scotia.

N. flexuosa, cordata, and angustifolia. 
They are plentiful both in the anthracite region at Mans- 
. field, Massachusetts, and in Nova Scotia ; but from the former 
locality I have several perfectly orbicular, detached leaves, which 
probably belong to N. heterophylla. Brongniart’s idea of the 
fossil fructification of this fern is now known to be erroneous. 
On almost every specimen, from both the above localities, 
fine lines may be discovered, crossing the veins at an obtuse 
angle, and almost parallel with the midrib; they are very cleat 
under the microscope. Although these lines crossing the 
veins may hardly be supposed to be fructification ; yet, as they 
occur on no other fossil leaves, they are worthy of attention 
and consideration.

in the coal mines of Lardin, near Terrasson, in France, cannot

diminished about one-third. I have already stated my doubts 
as to many of the Neuropterides, and particularly of Cyclopte- 
ris, belonging to the Filices, suspecting them rather to be 
Conifers. "The knots, or joints, on the stem, are so strongly 
marked in Brongniart’s figure, as well as in the specimens
