vi PREFACE. 
for the never-tiring zeal and energy, the self-denial of all 
home-comforts, and risk of health displayed by the pioneers 
of our common science in the Australian colonies, and of whose 
work, often carried on under the most adverse circumstances, 
the Catalogue is an epitome. 
I refer to such men as the late S. Stutchbury, the late 
Rev. W. B. Clarke, F.R.S., the late Capt. Sturt, the late 
Sir T. L. Mitchell, the late L. Leichhardt, A. R. C. Selwyn, 
F.RS., C. Gould, F.G.S., Prof. F. M°eCoy, F.GS., the late 
W. Blandowski, Baron F. von Mueller, the late C. D’Oyly, H. 
Aplin, Norman Taylor, G. H. F. Ulrich, F.G.S., R. B. Smyth, 
F.G.S., the late R. Daintree, F.G.S., C. S. Wilkinson, F.G.S.,. 
Rey. J. E. T. Woods, F.G.S., R. A. F. Murray, H. Y. L. Brown, 
A. W. Howitt, F.G.S., G. Krefft, and others. 
The object of the Catalogue of Australian Fossils is first, 
to give as complete a list as possible of the fossil Organic 
Remains of the Australian Continent, arranged in Strati- ~ 
graphical and Zoological order; secondly, to indicate all the 
descriptions, figures, and more important references to each 
of the species; and thirdly, to point out the principal localities. 
In carrying out this scheme it has been found most con- 
venient to divide the Catalogue into five stratigraphical sub- 
divisions, viz., Silurian, Middle and Upper Paleozoic (including 
the Devonian and Carboniferous), Mesozoic, Tertiary, and 
Post-Tertiary, in each of which the genera and species are 
arranged zoologically in classes, and alphabetically in order, for 
convenient reference. | 
Each page is subdivided vertically into four columns. 
The first (that on the left hand of the reader) contains 
the name of the species and their authors; the second column 
is intended for the stratigraphical subdivisions of the respective 
sections in which the species occurs; the third and largest 
column is devoted to the bibliographical references, whilst 
the fourth contains the localities, 
At the head of each page, on the left hand, is given in dark 
type and within brackets the name of the class to which all 
the genera contained in that page belong, whilst, in the ~ 
corresponding corner, on the opposite side of the page, is 
similarly given the geological section of the work. 
After the name of each genus is given that of its author
