separate components of which amount to about five. It would 
be unsafe to assume that the large paired ovate leaves did not exist 
in this form, but no evidence is seen in the ])resent series, whilst 
the leaflets are comparativelv abundant. 
It is just |)()ssible that the specimens figured l)v Keistmantel 
as Schizoneiira (loHdv'anetms^'' from the Damuda Series, and 
associated with a flora of Triassic affinities represent an undescribed 
form and more nearly related to the above. S', niwrophi/lla. In 
these figures the leaf whorls are shown to be more irregularly divided 
into several linear or wedge-shaped leaves, which ai‘e characderistically 
split at the apex. A comparison of this form with hgs, 1, d, and 7 
of the ])resent series shows a close resemblance where the leaflets 
of the latter are obtuse, or with a slight cleavage.

()bserv(dions. -The flexibility of the rachis and the almost ragged 
tips of the ])innules would preclude a reference of the above figured 
specimens to Shirley's H^phenopteris superba,^^ to which it otherwise 
bears some resemblance. It is difficult indeed to separate the two 
(i^enera on mere fragments, for the same type of venation occurs in 
both. The balance of evidence, however, seems in favour of a 
reference to Coniopteris because of the less rigid character above 
noted. Figure 28 re])resents the a])ical [lart of a {linnule with both 
acuminate anil blunted tips to the lobes. Figure 24 has the bases 
of the pinnules e.xjianded, and they are not .so deeply incised as in 
Walkom’s figure 2 on plate X. ; but this may be the result of des- 
sication before fossilization.
