the reverse. They apparently belong to the same species, and seem to have 
been detached before maturity from their pedicels, whose remains are still 
marked by dark lines, fig. 8, fig. 9, enlarged twice, and fig. 10, enlarged about 
ten times. In this last figure dark but absolute lines are seen, apparently show¬ 
ing the suture of walls. In the pinnately divided part of the frond, fig. 6, ah 
the sort are opened, and their envelope is still attached to short pedicels, appa¬ 
rently placed opposite to each other. The details of the form of the sporanges 
are easily recognized, but those of their ramifications, or the point and mode of 
attachment of the son are rendered indistinct by the superposition of the groups 
of sporanges. The specimen is on shale from Morris, and was contributed by 
Mr. Jos. Even. \y \

This species lias a bi-pinnate frond, as seen on a specimen 
from the sliales of the coal at Morris, too large to be figured 
The divisions are alternate ; the thick secondary rack is is de¬ 
current on the main stem, which is also broad and smooth. 
The double celled sporanges are linear, attached by their backs, 
and pressed against each other in horizontal rows. The en¬ 
larged pedicel of the sporange cells is, before maturity, appa¬ 
rently at least, folded in the middle, and both rows of spo¬ 
ranges are joined together by their back, forming in that state 
slightly scythe-shaped cylinders, obtuse at both ends, attached 
to the pedicel by a dorsal membrane, and marked all around 
by the ring-like outlines of sporanges (fig. 3a). More gener¬ 
ally the sporange-cells are open side by side on each side of the 
dorsal support, and the sporanges appear then in two convex 
rows, fig. 4 and 5. In some specimens on concretions from 
Mazon creek, where small branches of this remarkable species 
are finely preserved, the sori or sporange bearing cells are deep¬ 
ly immersed in the stone, generally leaving around them an 
empty space, as seen in fig, 3 b and 3c; they are thus isolated 
and their form is easily ascertained. No traces of leaflets 
have been seen in connection with this species, which has as 
yet been obtained only from Morris and from Mazon creek.
