Angiopteridium spathulatum, McClelland. 
(Nos. 249, 250, 351, 253-55, 262, 364-67, 369, 372, 381, 406, 434, 443 r 
451, 461, 466.) 
Obs. —The fronds of this fern are known to Victorian geologists as 
Tceniopteris Daintreei , McCoy,* * * § but I still see no reason to modify my 
previously expressed opiniont that it and a form common throughout the 
Ipswich formation of Queensland are nothing more than local varieties of 
the previously described Angiopteridium spathulatum , McClelland. So far 
as the Queensland leaves are concerned, Mr. J. Shirley} coincides in this 
view, but he considers those from Victoria to be distinct. On the other 
hand, Mr. W. S. Dun,§ who has ably epitomised the whole of the Aus¬ 
tralian Tasniopteridse, agrees with my view, and has so cogently 
answered Mr. Shirley’s criticisms that further comment from me is wholly 
unnecessary. 
I should not have referred to this subject had not Mr. J. Stirlingj| revived 
it. It is, in my opinion, quite possible, by assembling a sufficient number 
of specimens from different localities, to so bridge over the apparent 
differences relied on by Mr. Stirling that his view of the matter simply 
becomes untenable. The differences between “ spathulate ” and u linear,” 
or “ slightly linear-lanceolate ” are so small as not to warrant a separation 
into two species at least. If such trivial points were allowed to weigh in 
the determination of fossil plants, under the circumstances named, every 
specimen would become a species. A comparison of McCoy’s original 
figures and Mr. Stirling’s more recent drawings are sufficient to show that 
the width of the midrib is of little or no moment. 
Amongst the Jumbunna East specimens (Nos. 372 and 451) is an in¬ 
teresting example of vernation. It is quite possible that this may be the 
young uncoiled condition of the frond of Angiopteridium spathulatum. A 
few faint striations are visible on the edges, that may indicate the veins. 
To speak broadly, I have little doubt that it is the vernation of an 
Angiopteridium at least. 
Loc .—Kilcunda District, Jumbunna East. 
Angiopteridium Etheridgei, Shirley. 
(Nos. 360, 370.) 
Obs. —From the Ipswich formation of Queensland Mr. J. Shirley has 
described^ a leaf, honoring me with the specific name, on the supposition 
that it is probably identical with a specifically undetermined form from the 
same formation, figured** by myself. On this point, however, I feel doubt¬ 
ful, but, be this as it may, there are two portions of leaves in the 
present collection that are, in all probability, Shirley’s species, distinguished 
by their very close veins and the high angle at which they leave the mid¬ 
rib. They are certainly not Angiopteridium spathulatum , and I know^ no 
other than the above to which they bear so close a resemblance.
