two beils a,re known. Glossopteris occurs with Pecopteris Australis, Phytlotheca, and the 
most important, with Teenio-pts Daintreei, McCoy. (McCoy: Prodrome* Decad. II, p. 15 : 
Report of Progress, Geol. Survey, Victoria, 1874, p. 25). 
As to 3 and 4, of which the first are the upper coal-measures of Newcastle, Mr, Blanford 
himself (p. 83) says, “ Nos. 3 and 4 appear to be connected by the presence of Glossopteris 
Browniana in both, although there appears to he a considerable distinction in the flora!’; 
and I would add, No. 3 does not contain any animals, while in No. 4 marine animals are 
found abundantly.* 
On page 84 Mr. Blanford enumerates the species, which, as he considers, are com¬ 
mon lo our Damudas and the Australian beds, and others which are common to the 
Damudas and the triassic rocks in Europe (as I pointed out). On these I would 
remark— 
Glossopteris (two or three species identical, W. T. B.)—I think with great 
difficulty we may be able to get only one common species. 
Gangamopteris (the genus only. W. T. B.).—This form is not known at all from 
those beds intercalated with marine fossils, but from really mesozoic beds in 
Victoria, associated with Tamiopteris Daintreei, McCoy. 
Vertebraria (one species identical. W. T. B.)—There is as yet no full description of 
the Australian Vertebraria, and that which is known seems to be quite different 
from ours. The greatest portion of our Damuda Vertebraria are probably not 
identical with those from Australia. 
Pecopteris (Alethopteris) (one species probably identical. W. T. B.)—I doubt 
whether our Alethopteris Bindley ana can be united with Alethopt. Australis, 
McCoy; or if this is altogether the case with any other species. 
Thus it seems that the evidence of a connection with the Australian coal-measures 
is very weak, while the fossils enumerated as common with European Trias are unmistakably 
identical. 
As to the stratigraphy of the Australian coal strata— the literature is not poor; but 
yet it is not iu all points quite clear and always trustworthy. 
It is well known that there can he a complete concordance in the stratification of rocks, 
and yet two or more different formations may be represented which can only be dis¬ 
tinguished by the prevailing fossil forms. As an instance I can qnote the Suit Range in 
India, where, as Mr. Wynne tells us, the lower marine carboniferous and the triassic rocks 
are conformably deposited; and yet they are different in age, although a well marked 
Ceratites and Phylloceras goes down into the carboniferous rocks, and marked forms 
of Belerophon survived into the Trias. The same relations will have to be applied to the 
two portions of the Australian coal-measures, only that hero the case is illustrated in the 
flora. 
For the stratigraphical grouping of the coal-strata of New South Wales we must 
especially take Mr. W. B. Clarke’s observations, which to a great extent are published :f partly 
Mr. Clarke communicated them to me in two letters, and he sent also a suite of fossils for 
* I speak of this further on.
