7. Clarence River Series. — These are described by Mr. C. S. Wilkinson. 
(No. 2S), as follows : — 
“ In the northern district of the Colony, on the Clarence llivcr, occurs 
a scries of coal-hearing shales, conglomerates, and sandstones, containing 
fossil plants allied to Tceniopteris and Pccoptcris, supposed to be of Mesozoic 
age. These beds have been described as being a long way above the New- 
castle Glossoptcris beds, and to have little in common with them. They 
belong to a different series which may eventually be collated with the Mesozoic 
coal strata of Victoria.* 
This appears from the fossils to bo really the case. From specimens 
which Mr. Clarke had sent me I could determine the following fossils : — 
Tceniopteris Dcdntreei , M‘Coy (the true species as described by 
M‘Coy). Southgate, Clarence River. 
Alethopteris australis, Morris. Southgate, Clarence River. 
It appears that these represent the Carbonaceous or higher Mesozoic 
beds of Queensland and Victoria. Age — Mesozoic- Jurassic.

* [During a recent examination (in April, 1889) of the Clarence River District, I discovered that its coal- 
bearing series, containing Tamiopteris and Alethopteris australis, is overlaid by beds of sandstone about 400 feet 
thick, identical with the Hawkesbury formation, which latter has been finally determined, upon the evidence 
of its fossil fauna, Labyrinthodons, Paheoniscus , Ac., to be of Triassic age. (Sec Clarke’s “Sedimentary 
Formations, N. S. Wales,” 4th edition, p. (i9.) It is not improbable, therefore, that the Victorian “Carbonaceous 
Series,” which, on account of their characteristic fossils Tce.niopteris Daintreci and Alethopteris australis, have 
hitherto been considered of Jurassic age, may be the equivalents of the Clarence Series as here suggested by 
Professor Feist mantel, and may also possibly be of Triassic age. — C. S.W.]
