sometimes slightly lobed (see fig. ii b). The upper pinnules have the lobes much 
more confluent, or are even nearly entire towards their apices. 
In the lower pinnules all the lobes are fertile, each bearing one thick, semi- 
circular sorus at the apex. The structure of the sori or of the sporangia cannot be 
m.ade out. The uppermost pinnules have no distinct sori, but the lobes are thick 
and entire and may represent an earlier stage of the fertile state (fig. 1 1 d). 
This specimen cannot well represent a fertile frond of Co 7 iiopteris hyincnophyl- 
loides. The habit of the (frond or) pinna with its almost perpendicular pinnules 
and the great length and linear shape of the latter are very unlike typical forms of 
that species. The greatest resemblance is to Bunbury’s type-specimen of Spheno- 
pteris nepJirocarpa, which, however, comes nearer to C. hyrnenophylloides than does 
the Antarctic specimen. If we bring the latter under Bunbury’s species, it would 
be more natural than before to keep this separate from C. Iiyme^iophylloidcs^ re- 
garding then the Antarctic specimen as the one more typical and better distinguished 
from the latter species. 
It is possible that this specimen is a fertile pinna of the frond described below 
as Coniopteris lobaia. At least there is a great resemblance in habit, the fertile 
specimen having only a little narrower pinnules. Oldham & MORRIS (1863, pi. 28), 
however, have figured fertile fronds of that species, in which the pinnules and sori 
are somewhat different from those of our specimen. Feistmantel (1877 rt-, P- 4 °) 
remarks, it is true, that the figures are incorrect, the sori being more on the mar- 
gin (as in the present form); but for the present it seems best to use Bunbury’S 
non-committing name.

A few specimens of a large and fine bipinnate fern-frond seem to belong to 
this little known Indian species. 
The largest specimen is the lower one shown in text-fig. 5 - It measures more 
than II cm. in breadth without being complete. The other one shown in the same 
figure, is smaller and probably belongs to the upper part of the frond; but still it 
is of considerable dimensions. The rachis is slender in respect to the size of the 
frond, and so are the rachises of the pinnæ. The pinnæ are long and narrow, 
lanceolate or linear, attached at a wide angle. The pinnules are ovate to ob- 
long, mostly with more or less parallel sides, and tapering rapidly to an obtuse
