12 MR. NEWELL ARBER ON THE CLARKE COLLECTION  [ Feb. 1902, 
correspond very closely with any of Feistmantel’s figures. The type 
occurs with Gilossopteris Browniana on the same slab. The larger 
specimen of the figured types is 23 inches long. Here again 
further specimens are necessary, before attempting to establish this © 
species as distinct from other Australian Sphenopteridee.

There is a large specimen in the collection of a fern, which is in 
association with Gilossopterzs, but without record as to locality. 
From the character of the rock, however, we may infer that the 
specimen was in all probability obtained from Mulubimba. It con- 
sists of a portion of a large tripinnate frond, with a stout rhachis 
7 inches long, bearing alternate primary pinne, 5 or more inches 
long. The secondary pinne average 13 inches in length, and 3 inch 
in breadth, and consist of crowded, and, in parts, imperfectly pre- 
served and indistinct pinnules. In places, however, the form and 
nervation of the pinnules is shown very clearly, and these appear to 
be identical with certain forms of the Indian fern Sphenopteris 
polymorpha, figured and described by Feistmantel.’ 
There are also several small fragments of a delicate frond, from the 
shale of Mulubimba (Pl. I, figs. 4 & 5), which resemble very closely 
in form and nervation the specimens figured by Feistmantel as 
Sphenopteris polymorpha.? 
It will be remembered that specimens of Sph. fleauosa were stated 
(p. 11) to bear a general resemblance to Sph. polymorpha.  Feist- 
mantel * has also compared certain pinnules of Sph. alata (Brongt.) 
with the same plant. It seems certain, therefore, that Sph. poly- 
morpha of India occurs also in Australia, although neither Feist- 
mantel nor Tenison-Woods has recorded it. This, again, is another 
point of contact between the Newcastle Beds and the Lower 
Gondwanas of India.

2 Feistmantel (81) vol. iii, pl. xvi a is, figs. 2,2 a, & 3. I believe that the 
specimens identified by Tenison-Woods (83) p. 114 & pl. vi, figs. 2 & 3, as 
Merianopteris major, should also be referred to this species.
