discovered a very interesting series of finely laminated 
carbonaceous shales, which proved to be rich in plant remains. 
Various species of ferns of a newand interesting character 
were obtained belonging to the genera Pecopteris, Thinnfeldia, 
Odontopteris, Tzeniopteris. One splendid specimen, with 
ovate lanceolate pinnules, which have peculiar laciniate 
margins, is peculiarly interesting, and may prove to belong to 
the genus Otopteris. 
The distribution shows nothing but the remains of Phyllo- 
theca and Zeugophyllites in certain beds and localities, while in 
contiguous or closely related beds hardly any other forms 
than those of Pecopteris, Thinnfeldia, and Teniopteris, 
therefore great caution must be exercised for the present 
in separating beds of this system upon the evidence of organic 
remains only. 
The restriction of particular forms to particular beds 
may only indicate a slight local difference in vegetation 
rather than difference in age or even horizon. However, on a 
future occasion, I will deal more fully with this important 
subject, for which Iam now provided with many rich and 
interesting materials. 
In conclusion, I draw attention to figures of some of the 
new plant forms from Spring Hill, Porter Hill, and the 
lower coal measures of the Mersey. The large imperfect 
frond from the Porter Hill beds, cythere shales, appears to 
belong either to the genus Cyclopteris or Gangamopteris. 
The spathulate frond found associated with Glossopteris 
Browniana from the lower coal measures of the Mersey is, I 
believe, identical with Noeggerathiopsis media of New South 
Wales. 
The large equisetaceous impression from the same 
place, at the Mersey, is closely allied, if not identical, 
with a form of Schizoneura, figured by Feistmantel from the 
Lower Gondwana series, India.

Mount Wellington, on the 10th March last, close to a clear
