Art. XXXIV. On the Fossil Botany and Zoology of the Rocks 
associated with the Coal of Australia. By Frederick 
M’Coy, M.G.S. & N.H.S D. &c. 
[From the Annals and Magazine of Natural History, No. 132, September, 1847.] 
The following paper has been drawn up from an examination of 
specimens collected by the Rev. W. B. Clark and sent to the 
Rev. Prof. Sedgwick, who kindly allowed the writer to make this 
use of them. 
The species will be first noticed, and the new forms described, 
after which some observations will be offered on the relative ages 
of the Australian coal-fields, from a comparison of their organic 
remains with each other, and with those of other countries; pre¬ 
mising that the extent of our materials enables this to be at¬ 
tempted in a more extended and precise manner than heretofore, 
and that several of the new forms described are calculated to 
throw much light on the fossils of our own country. 
In this first part of my paper I wish to express my obligations 
to the Rev. Prof. Henslow and Mr. Babington for the kindness 
with which they allowed me the use of their herbaria on all oc¬ 
casions when I found it necessary to work out for myself points 
of structure in recent plants, neglected by botanists and omitted 
in their works, but which are of the highest importance in the 
investigation of fossil plants. To the facilities afforded by the 
former for my examination of the New Holland plants growing 
in the houses of the Cambridge Botanic Garden, I am mainly 
indebted for the maturing my views of the affinities of the genus 
Phyllotheca.
